Can I checkbox id in array in wp_query for WordPress?

Edit——–
Problem solved, see my reply below for the code!

Sorry for bad English.
I’m making changes to a theme in order to provide the ability to make bulk changes from the dashboard front-end.
I’ve already managed to provide the same functionality for individual posts, through simple buttons, a function and a little bit of JS.

Now I would like to do the same thing in bulk, but if before reading the IDs of each post it was the button, now it must be a checkbox, which will have to return as an array of IDs to the function.

I did some tests and the code works, not totally.

Because now I can perform the action, but only for a single post, even if I check all post, it performs the action only for the first post checked.

I guess it’s a write error in the function in php, I should pass it the propID values ​​as an array, or do a foreach for each (lol) post. But I didn’t quite understand how to do it, do you have any suggestions?

This is my code:

button:

 <button type="button" class="multi-on-hold btn btn-primary btn-sm">Premi</button>

checkbox:

<input type="checkbox" class="multicheck_prop" name="multicheck_prop[]" value="<?php echo ($post->ID); ?>">

function:

add_action( 'wp_ajax_multicheck_houzez_on_hold', 'multicheck_houzez_on_hold' );

if ( !function_exists( 'multicheck_houzez_on_hold' ) ) {
    function multicheck_houzez_on_hold() {

        if ( isset( $_POST['propID'] ) ) {

            global $wpdb;
            if (! isset( $_POST['propID'] ) ) {
                wp_die('No post to put on hold has been supplied!');
            }
            $post_id = absint( $_POST['propID'] );
            
            $post_status = get_post_status( $post_id );

            if($post_status == 'publish') { 
                $post = array(
                    'ID'            => $post_id,
                    'post_status'   => 'on_hold'
                );
            } elseif ($post_status == 'on_hold') {
                $post = array(
                    'ID'            => $post_id,
                    'post_status'   => 'publish'
                );
            }
            $post_id =  wp_update_post($post);
        }
            return true;
    }
}


js: 

    

            $('.multi-on-hold').on( 'click', function( e ) {
            e.preventDefault();
            var $this = $( this );
            var propid = $this.data( 'property' );
            var checkboxVals = $('.multicheck_prop');
    
            var vals = $('.multicheck_prop:checked').map(function(){return this.value;}).get().join(',')
    
            if(vals == "") {
                return;
            }
            
            $.ajax({
                
                url: ajax_url,
                data: {
                    'action': 'multicheck_houzez_on_hold',
                    'propID': vals,
                },
                method: 'POST',
                dataType: "JSON",
                
                beforeSend: function( ) {
                    //window.alert(vals)
                    houzez_processing_modal(processing_text);
                },
                success: function( response ) {
                    window.location.reload();
                },
                complete: function(){
                }
            });               
        });
