Add product custom field in product grid

Hi,

I want to add a custom field of products in the WooCommerce product grid.
Now I have this code but this adds it on the product page while I want to show it in the grid;

add_action( 'woocommerce_after_single_product_summary', 'add_custom_field', 0 );

function add_custom_field() {
    global $post;
 
	echo "<div class='prod-code'>Product Code: ";
	echo get_post_meta( $post->ID, '_yith_booking_block_cost', true );
	echo "</div>";

    return true;
}
