Rename Sidebar „Add New“ Label

In the Total theme i.e. for the portfolio or staff custom post types, the menu labels are not properly translated. This is how to fix this:

add_filter('register_post_type_args', function($args, $post_type) {

    if ($post_type === 'portfolio') {

        $args['labels']['add_new'] = 'Neu';
        $args['labels']['add_new_item'] = 'Film hinzufügen';

    }

    return $args;

}, 10, 2);
