How to add custom plugin data to the cart in woocommerce using custom button on product page?

I am implementing the custom Buy Now button in my plugin. I had placed the Buy Now button on the product page using this hook

  add_action( 'woocommerce_after_add_to_cart_button', 'myCustomBuyNowButton');

So, my next step is to add the product to the cart with quantity, variation details, which I am able to achieve by writing the following function i.e

(function ($) {

$(document).on('click', '.single_add_to_cart_button', function (e) {
    e.preventDefault();

    var $thisbutton = $(this),
    $form = $thisbutton.closest('form.cart'),
    id = $thisbutton.val(),
    product_qty = $form.find('input[name=quantity]').val() || 1,
    product_id = $form.find('input[name=product_id]').val() || id,
    variation_id = $form.find('input[name=variation_id]').val() || 0;

    var data = {
        action: 'woocommerce_ajax_add_to_cart',
        product_id: product_id,
        product_sku: '',
        quantity: product_qty,
        variation_id: variation_id,
    };

    $(document.body).trigger('adding_to_cart', [$thisbutton, data]);

    $.ajax({
        type: 'post',
        url: wc_add_to_cart_params.ajax_url,
        data: data,
        beforeSend: function (response) {
            $thisbutton.removeClass('added').addClass('loading');
        },
        complete: function (response) {
            $thisbutton.addClass('added').removeClass('loading');
        },
        success: function (response) {

            if (response.error && response.product_url) {
                window.location = response.product_url;
                return;
            } else {
                $(document.body).trigger('added_to_cart', [response.fragments, response.cart_hash, $thisbutton]);
            }
        },
    });

    return false;
});
})(jQuery);

& ajax is calling the following hook

add_action('wp_ajax_woocommerce_ajax_add_to_cart', 'woocommerce_ajax_add_to_cart');
add_action('wp_ajax_nopriv_woocommerce_ajax_add_to_cart', 'woocommerce_ajax_add_to_cart');

function woocommerce_ajax_add_to_cart() {

$product_id = apply_filters('woocommerce_add_to_cart_product_id', absint($_POST['product_id']));
$quantity = empty($_POST['quantity']) ? 1 : wc_stock_amount($_POST['quantity']);
$variation_id = absint($_POST['variation_id']);
$passed_validation = apply_filters('woocommerce_add_to_cart_validation', true, $product_id, $quantity);
$product_status = get_post_status($product_id);

if ($passed_validation && WC()->cart->add_to_cart($product_id, $quantity, $variation_id) && 'publish' === $product_status) {

    do_action('woocommerce_ajax_added_to_cart', $product_id);

    if ('yes' === get_option('woocommerce_cart_redirect_after_add')) {
        wc_add_to_cart_message(array($product_id => $quantity), true);
    }

    WC_AJAX :: get_refreshed_fragments();
} else {

    $data = array(
        'error' => true,
        'product_url' => apply_filters('woocommerce_cart_redirect_after_error', get_permalink($product_id), $product_id));

    echo wp_send_json($data);
}


wp_die();
}

But I am stuck in adding the custom plugin data to the cart along with the quantity and variation details.

For ex: If the admin has installed a custom product fields plugin that helps them to add the custom fields on their product page to collect extra information. I need to add that information also to the cart.

Can anyone please help me to resolve this issue? Thanks in advance.

    Use these hooks

    // Add item data to the cart or define custom variable
add_filter( 'woocommerce_add_cart_item_data', 'add_cart_item_datax',10, 3 );

// Display item data to the cart or show custom variable
add_filter( 'woocommerce_get_item_data', 'get_cart_item_data', 10, 2 );


function add_cart_item_datax( $cart_item_data, $productId, $variationId ) {

    if ( empty( $cart_item_data['basicpluginstr'] ) ) {
            $cart_item_data['basicpluginstr'] = array();
    }

    $data[] = array(
            'name'  => 'Name',
            'value' => 'valus',
            'price' => 50
            );
            
    $cart_item_data['basicpluginstr'] = array_merge( $cart_item_data['basicpluginstr'], $data);

    return $cart_item_data;
}


function get_cart_item_data( $data, $cartItem ) {

    if ( isset( $cartItem['basicpluginstr'] ) ) {

        foreach ( $cartItem['basicpluginstr'] as $basicpluginstr ) {

            $name = 'PPPPPPP'; //$basicpluginstr['name'];  

            $value = '12364'; //$basicpluginstr['value'];  

            $price = '150'; //$basicpluginstr['price']; 

        }

        $data[] = array(
            'name' => $name,
            'value' => $value,
            'display' => 0
        );
    }

    return $data;
}


//Add meta to order - WC 2.x or save the data when the order is made
add_action( 'woocommerce_add_order_item_meta',  'add_order_item_meta' , 10, 2 );
function add_order_item_meta( $item_id, $values ) {
   
      if ( ! empty( $values['basicpluginstr'] ) ) {
          foreach ( $values['basicpluginstr'] as $basicpluginstr ) {

              $name = $basicpluginstr['name'];
              $value = $basicpluginstr['value'];
              woocommerce_add_order_item_meta( $item_id, $name, $value );

              //woocommerce_add_order_item_meta( $item_id, 'basicpluginstr', 'basicpluginstr value' );
          }
      }
