Answer 1

You can use checkChatInvite:

from telethon.sync import TelegramClient
from telethon import functions, types

with TelegramClient(name, api_id, api_hash) as client:
    result = client(functions.messages.CheckChatInviteRequest(
        hash='A4LmkR23G0IGxBE71zZfo1'
    ))
    print(result.stringify())
