I am trying to display user on query but i want to display order by user role. Suppose we have 2 user role, Gold and Free. I want to display Gold user first and then free users.

$args = array(
                'order'      => 'ASC',
                'orderby'    => 'display_name',
                'role__not_in' => 'administrator',
                'posts_per_page' => 10,
                'meta_query' => array(
                    'relation' => 'OR',
                    array(
                        'key'     => 'pin_code',
                        'value'   => sanitize_text_field($_GET['pin_code']),
                        'compare' => 'LIKE'
                    ),
                    array(
                        'key'     => 'city',
                        'value'   => sanitize_text_field($_GET['pin_code']),
                        'compare' => 'LIKE'
                    ),
                    array(
                        'key'     => 'county',
                        'value'   => sanitize_text_field($_GET['pin_code']),
                        'compare' => 'LIKE'
                    ),
                )
            );

            // Create the WP_User_Query object
            $wp_user_query = new WP_User_Query($args);

i dont know how to achieve this in query arg.
