Sitemap didnot include multi-languages category

Anyone face this can add this code to theme function:

/**
* Get all terms in all languages when the language is set from the content or directory name
*/
add_filter( ‘get_terms_args’, ‘rank_math_remove_terms_filter’ );
function rank_math_remove_terms_filter( $args ) {

if ( isset( $GLOBALS[‘wp_query’]->query[‘sitemap’] ) ) {
$args[‘lang’] = ”;
}

return $args;

}
