Is there any possibility to keep a remove button from in the list of liked posts (current-user-likes.php) In this is there any option to keep remove button for each liked post to remove individually.

Removing liked posts from page template not working. But added same code how it was for posts page.

<?php
/*
* Template Name: Liked Posts
*/
get_header();
$current_user = get_current_user_id();
?>
	<table class="form-table">
		<tr>
			<th><label for="user_likes"><?php _e( 'You Like:', 'YourThemeTextDomain' ); ?></label></th>
			<td>
			<?php
			$types = get_post_types( array( 'public' => true ) );
			$args = array(
			  'numberposts' => -1,
			  'post_type' => $types,
			  'meta_query' => array (
				array (
				  'key' => '_user_liked',
				  'value' => $current_user,
				  'compare' => 'LIKE'
				)
			  ) );		
			$sep = '';
			$like_query = new WP_Query( $args );
			if ( $like_query->have_posts() ) : ?>
			<p>
			<?php 
            
 while ( $like_query->have_posts() ) : $like_query->the_post(); 
 echo $sep; 
 $post_id = get_the_ID();
 $nonce = wp_create_nonce( 'simple-likes-nonce' );
 $is_comment = '0';
?>
 <a href="<?php the_permalink(); ?>" title="<?php the_title_attribute(); ?>">
 <?php the_title(); ?></a> 
 <?php echo  $post_id; ?>
 <a href="<?php echo admin_url( 'admin-ajax.php?action=process_simple_like' . '&post_id=' . $post_id . '&nonce=' . $nonce . '&is_comment=' . $is_comment . '&disabled=true') ?>">Remove</a>
 <?php echo do_shortcode('[jmliker]'); ?>
			<?php
			$sep = ' &middot; ';
			endwhile; 
			?>
			</p>
			<?php else : ?>
			<p><?php _e( 'You do not like anything yet.', 'YourThemeTextDomain' ); ?></p>
			<?php 
			endif; 
			wp_reset_postdata(); 
			?>
			</td>
		</tr>
	</table>
<?php get_footer(); ?>
