Make comments load on click on wordpress button?

Question

Web development

Greetings!
Unable to load comments on button click.
That is, you need to display 5 comments, and the download button, by clicking on which we display 5 more, etc.
I receive comments like this: (this is already when we clicked to load more comments)

<?php
$args_list = array(
    'callback' => 'mytheme_comment',
  );
  $args = array(
    'order' => 'ASC',
    'offset' => $offset,
    'number' => $items,
    'post_id' => $post_id,
  );
  $comments = get_comments($args);
  wp_list_comments($args_list, $comments);
?>

Accordingly, the required values ​​are passed to the offset and number post_id parameters.
But when using the number parameter, the tree view (nesting) of comments is violated.
