[Support request] how to make Previous and Next post navigation as like on Dispatch single post

Hi there,

Dispatch uses a Hook Element containing this code:

<div id="post-nav">
	<?php 
	global $post;
	$prevPost = get_previous_post(false);
	$post_type = get_post_type();
	
	if ( $prevPost ) {
		$args = array(
			'posts_per_page' => 1,
			'include' => $prevPost->ID,
			'post_type' => $post_type,
		);
		
		$prevPost = get_posts($args);
		foreach ($prevPost as $post) {
			setup_postdata($post);
			?>
				<a class="post-previous" href="<?php the_permalink(); ?>">
					<div class="post-nav-wrap" style="background: linear-gradient(0deg,rgba(52,62,71,0.1),rgba(52,62,71,0.3)),url('<?php the_post_thumbnail_url(); ?>');">
						<div class="post-nav"><?php _e( 'Previous', 'generatepress' ); ?></div>
						<h3 class="post-nav-title"><?php the_title(); ?></h3>
					</div>
				</a>
			<?php
			wp_reset_postdata();
		} //end foreach
	} // end if
         
	$nextPost = get_next_post(false);
	
	if ( $nextPost ) {
		$args = array(
			'posts_per_page' => 1,
			'include' => $nextPost->ID,
			'post_type' => $post_type,
		);
		
		$nextPost = get_posts($args);
		foreach ( $nextPost as $post ) {
			setup_postdata($post);
			?>
				<a class="post-next" href="<?php the_permalink(); ?>">
					<div class="post-nav-wrap" style="background: linear-gradient(0deg,rgba(52,62,71,0.6),rgba(52,62,71,0.3)),url('<?php the_post_thumbnail_url(); ?>');">
						<h3 class="post-nav-title"><?php the_title(); ?></h3>
						<div class="post-nav"><?php _e( 'Next', 'generatepress' ); ?></div>					
					</div>
				</a>
			<?php
			wp_reset_postdata();
		} //end foreach
	} // end if
?>
</div>

And here’s the settings for it:

It also removes the post navigation on the customizer settings.
