JavaScript — Как изменить вызов для идентификатора пользователя WordPress на вызов для отображаемого имени пользователя

Я работаю над модификацией этого плагина, чтобы сделать его более подходящим для моих нужд. Однако у меня были огромные проблемы с переключением с него с помощью идентификатора пользователя на отображаемое имя пользователя. Я включил оригинал и мои правки ниже. Любая помощь или рекомендации с благодарностью!
