The metabox for displaying all post comments on the Edit Comment page in WordPress doesn't work, why?

Question

WordPress

Good day. Regularly, the metabox is displayed on the post edit page, but I also wanted to add it to the "Edit comment" page, i.e. so that all comments that relate to the post to which the edited comment belongs are displayed. Function code borrowed from here . But for some reason it does not work - it does not show comments, although they are definitely there.

<?php
add_action( 'admin_menu', 'all_display_comments_add_meta_box' );

function all_display_comments_add_meta_box() {
    add_meta_box( 'commentsdiv', __( 'Comments' ), 'my_post_comment_meta_box', 'comment', 'normal', 'high' );
}

function my_post_comment_meta_box( $post ) {

    $total         = get_comments(
        array(
            'post_id' => $post->ID,
            'number'  => 1,
            'count'   => true,
        )
    );
    $wp_list_table = _get_list_table( 'WP_Post_Comments_List_Table' );
    $wp_list_table->display( true );

    if ( 1 > $total ) {
        echo '<p id="no-comments">' . __( 'No comments yet.' ) . '</p>';
    } else {
        $hidden = get_hidden_meta_boxes( get_current_screen() );
        if ( ! in_array( 'commentsdiv', $hidden, true ) ) {
            ?>
            <script type="text/javascript">jQuery(document).ready(function(){commentsBox.get(<?php echo $total; ?>, 10);});</script>
            <?php
        }

        ?>
        <p class="hide-if-no-js" id="show-comments"><a href="#commentstatusdiv" onclick="commentsBox.load(<?php echo $total; ?>);return false;"><?php _e( 'Show comments' ); ?></a> <span class="spinner"></span></p>
        <?php
    }

    wp_comment_trashnotice();
}

How will it be right?

To begin with, this is only part of the functionality. And not always the functionality from one page is applicable to another. In any case, I think it will be easier to write it yourself than to fix what should not be there (especially if you are not good at it).

... not working, why?

The thing is, the comments page is not the posts page. On the posts page, the variable function my_post_comment_meta_box( $post ) { is passed inside the function, which contains the post data. On the comments page, the comment data will fly there. And this is a completely different matter.
Minimize the code to make it easier to understand and then build up to the desired functionality, sorting out the functions along the way ...
I.e. Roughly speaking, it should be something like this:

don't forget about var_dump - very useful thing

function my_post_comment_meta_box( $comment ) {
    $total=get_comments(
        array(
            'post_id' => $comment->comment_post_ID,
        )
    );
    foreach($total as $mass){
      var_dump($mass);
      echo '<a href="'.get_site_url().'/wp-admin/comment.php?action=editcomment&c='.$mass->comment_ID.'">'.esc_html__('Редактировать','VAB').'</a>';
      echo'<br><br>Отступ м/у комментариями<br><br>';
    }
}

По сути остается эти данные переварить в нужную Вам разметку...
и додумать выборку

$total=get_comments(array('post_id'=>$comment->comment_post_ID,));

Более готовый и сложный вариант, думаю, никто Вам писать не будет. только, если плагины посоветовать, но это не ко мне ¯\_(ツ)_/¯ ...
