  $temp_array = [];
  for($i = 0; $i < count($orig_menu); $i++) {
    if( $orig_menu[$i]->children) {
      preprocess_wp_menu_for_twig($orig_menu[$i]->children);
    }
    $orig_menu[$i]->title = $orig_menu[$i]->name;

  $temp_array = [];
  for($i = 0; $i < count($orig_menu); $i++) {
    if( $orig_menu[$i]->children) {
      $this->preprocess_wp_menu_for_twig($orig_menu[$i]->children);
    }
    $orig_menu[$i]->title = $orig_menu[$i]->name;
    $orig_menu[$i]->link = $orig_menu[$i]->url;
  }
}
  
function add_to_context( $context ) {
...
//Add menus to context
  $primary_menu = new TimberMenu('primary'); 
  $this->preprocess_wp_menu_for_twig($primary_menu->items);
  $context['primary_menu'] = $primary_menu;
...
