Есть код получения и обработки медиа группы в канале телеграм ботом на aiogram 2, как сделать тоже самое на telebot?

Смотрел Middleware в telebot, все бы работало да не хватает поля conf класса TelegramObject, да и вообще класса TelegramObject. Пытался через updates, выскакивала ошибка: Error code: 409. Description: Conflict: terminated by other getUpdates request; make sure that only one bot instance is running, помогите реализовать эту идею на telebot..
