I want a read more button to appear at the end of the author description so whenever I click that the description expands and shows the rest of it. This is the code I have :

<div class="author-img">
<?php echo get_avatar(get_the_author_meta('user_email'), '100');  ?></div>
<h3 class="author-name">
<?php esc_html(the_author_meta('display_name'));  ?></h3>

<p class="author-description"><?php echo wp_trim_words(strip_tags(get_the_author_meta('description')),42,'...');  ?></p>

could you please help me to find a solution for this?

Thanks
