Get a list of child pages via a function in wordpress

I am trying to get a list of child pages to display on the parent page via wordpress. The best way I can describe what I am trying to do is if you are on the about page (/about) but you want to go to the meet the team page (/about/meet-the-team) when you are on the about page it should then display a link to the meet the team page.

I have this code at the moment

function getPagesHierarchy() {
    $pagesQuery = new WP_Query(array(
        'post_type'     => 'page',
        'posts_per_page' => -1,
        'post_parent'   => 0,
        'order'         => 'ASC',
        'post_status'   => 'publish'
    )) ;
    if ($pagesQuery->have_posts()) {
        while($pagesQuery->have_posts()) {
            $pagesQuery->the_post() ;
            the_title() ;
            echo '<br>' ;
        }
    }
    
}

What this is doing is it is getting a structure of the parent pages like this image shows below
enter image description here

This is currently getting all the parent pages which is fine however I also need it to display that parent pages children under it. so for example it would be something like this;

Any help with this would be much appreciated if I can give anything else to assist in what I am trying to achieve please do let me know.

    You can use wp_list_pages() and pass in the parent page ID with child_of to get its children. You can refer to the WP docs for more info.
    So that’d look something like

    wp_list_pages(array(
    'child_of' => $parentId
));

    Probably best to use get_pages()

    function getPagesHierarchy() {
    
    $pages = get_pages(array('parent' => 0)); 
    foreach ( $pages as $page ) {
        echo $page->post_title;
        echo '<br>' ;
        $child_pages = get_pages(array( 'child_of' => $page->ID)); 
        foreach ( $child_pages as $child_page ) {
            echo $child_page->post_title;
            echo '<br>' ;
        }
    }
}
