Description

Sometimes while using bound methods the method doesn't work however it may or may not throw errors.
I was using success = Message.chat.unban_member(user_id) and was printing success it is showing true in the console however user is not getting unbanned. This is the most recent example I have faced it few more times while using bound methods

Steps to reproduce

Use Message.chat.ban_member(user_id) then use Message.chat.unban_member(user_id)

Code example

from pyrogram.types import Message

@Client.on_message()
async def ban_memberss(_, m: Message):
    u_id = m.from_user.id
    await m.chat.ban_member(u_id)
    success = await m.chat.unban_member(u_id)
    print(success)

Logs

There are no errors for this code I am getting `True` in the console however the user is still banned
