How to make a request for recommended products in woo?

Question

WordPress

Can you tell me how to make a request for recommended products in woo using WP Query?
This method doesn't work..

$args = array(
        'meta_key' => '_featured',
        'meta_value' => 'yes',
        
        );


$featured_query = new WP_Query($args);

made the product featured, but the _featured field didn't even appear in the database in the wp_postmeta table, so this method doesn't work...
