Миграция моего обычного RecyclerView в привязку данных RecyclerView

Question

У меня есть проблема, когда я изменяю какое-то значение, например, удаляю комментарий в моем обзоре переработчика, он не обновляется автоматически, Google говорит, что используйте LiveData DataBinding RecyclerView, кто-нибудь когда-либо делает привязку данных RecyclerView LiveData, пожалуйста, помогите мне
