Multiple Author Box not displaying

Hello there. I want Co-Authors Plus plugin to display multiple authors in their individual author box with their individual description, image and name. I implemented your code in such manner in my theme code(Child theme) reading your Document: https://docs.wpvip.com/technical-references/plugins/incorporate-co-authors-plus-template-tags-into-your-theme/

But only the names of multiple author show up and individual author box with their individual description, image and name are not showing. What is the problem can you help?

<!– author box –>

         
<?php
$author_id = get_the_author_meta( 'ID' );
?>
                   
<?php   if ( function_exists( 'coauthors_posts_links' ) ) {
coauthors_posts_links();
} else { ?>
<div class="author-box-wrap">
<?php ?>
  
<a href="<?php echo esc_url(get_author_posts_url($author_id)) ?>">              
<?php echo get_avatar(get_the_author_meta('email', $author_id), '96') ?>
                        
</a>
                  

<div class="desc">
