[Resolved] Adding language switcher to mobile header

I am trying to add an extra language switcher to the mobile header part but cant get it to work i tried several codes in the function php file

function add_wpml_switcher_to_mobile_menu_bridge($items, $args) {
if ($args->theme_location === 'mobile_menu') {
$switcher_code = wpml_lang_switcher(['dropdown_items' => 3]); // Customize the number of dropdown items as needed
$items = '<li class="menu-item wpml-switcher">' . $switcher_code . '' . $items;
}
return $items;
}
add_filter('wp_nav_menu_items', 'add_wpml_switcher_to_mobile_menu_bridge', 10, 2);
