Hi,
I've been trying to call via the telegram API but after multiple attempts am still not able to figure it out. I found your code but I get this error

Traceback (most recent call last):
  File "makeCall.py", line 67, in <module>
    dh_config = get_dh_config()
  File "makeCall.py", line 64, in get_dh_config
    return DH(client.send(GetDhConfig(0, 256)))
TypeError: __init__() takes 1 positional argument but 3 were given

It would be of great help if you could help me out. Thanks
