I want to display popular post with rest API but I have no idea to get the posts with most viewed.

I use update_post_meta and fetch rout like code below.

<?php
function post_view_count() 
 if ( is_single() ) 
 $count = get_post_meta( get_the_ID(), 'post_view_count', true ) ?: 0;
 if ( ! $count ) 
 $count = 1; // if the meta value isn't set, use 1 as a default
 
 $count++;
 update_post_meta( get_the_ID(), 'post_view_count', $count );
 

add_action( 'wp_head', 'post_view_count' );
?>


<?php
 // Register a REST route
 add_action( 'rest_api_init', function () 
 //Path to meta query route
 register_rest_route( 'popular/v2', '/pp/', array(
 'methods' => 'GET', 
 'callback' => 'custom_meta_query_dinhmenh' 
 ) );
 );

 // Do the actual query and return the data
 function custom_meta_query_dinhmenh()
 // Set the arguments based on our get parameters
 $args = array (
 array(
 'relation' => $_GET['meta_query'][0]['relation'],
 'key' => $_GET['meta_query'][0]['key'],
 'value' => $_GET['meta_query'][0]['value'],
 'show_in_rest' => true, 
 //'compare' => '=',
 ), 
 );
 // Run a custom query
 $meta_query = new WP_Query($args);
 if($meta_query->have_posts()) 
 //Define and empty array
 $data = array();
 // Store each post's title in the array
 while($meta_query->have_posts()) 
 $meta_query->the_post();
 $data = get_the_title();
 
 // Return the data
 return $data;
 else 
 // If there is no post
 return 'No post to show';
 
 
?>

Can you help me to write condition to display most viewed posts based on post_view_count

Thank you so much.
