Create HTML filter for widget_recent_entries

Dear WordPress team,
Please insert a filter for widget_recent_entries list items.
for this part i mean:

<li><a href="<?php the_permalink( $recent_post->ID ); ?>"<?php echo $aria_current; ?>><?php echo $title; ?></a><?php if ( $show_date ) : ?>
<span class="post-date"><?php echo get_the_date( '', $recent_post->ID ); ?></span>
<?php endif; ?></li> 

To develop a thumbnail, for example, if necessary during development or something else.
