For some reason, AsyncTeleBot doesn't get updates from service messages. For example, I have a bot in a group. If I run this code and then I pin a message I get no result.

bot = AsyncTeleBot(BOT_TOKEN)

async def func_that_triggers_when_pinned(mess):
    print(mess)

bot.register_message_handler(func=(lambda x: True if x.pinned_message else False), callback=func_that_triggers_when_pinned)

import asyncio
asyncio.run(bot.polling())

Even if I just let func be True all the time, I get no update when the message is a service message i.e. someone joined the chat, someone left the chat, pinned message etc. If I run this, however, it works.

bot = telebot.TeleBot(BOT_TOKEN)

def func_that_triggers_when_pinned(mess):
    print(mess)

bot.register_message_handler(func=(lambda x: True if x.pinned_message else False), callback=func_that_triggers_when_pinned)

bot.polling()

I have even tried polling(allowed_updates=telebot.util.content_type_service) but it didnt work
