telethon library: how to add user by phone number

问题

I am studying Telethon library for Telegram that can act as a Telegram client using Telegram API (Important: this is Telegram client API, not Bot API).

The functionality I need is creating a group chat and inviting users there. This works fine when I add somebody who is in my contact list:

import telethon
from telethon.tl.functions.messages import CreateChatRequest
client = telethon.TelegramClient('some_session', 'key', '6284f5acf91b03somehash441ac9eef319')
client.start()
client(CreateChatRequest(['+79297226653'], 'Test Group')) # number from my contact list

However, this breaks if the number I pass is not in my contact list (an I am certain this phone number is registered with Telegram)

  File "/Users/1111/.virtualenvs/inviter-WB5rPISo/lib/python3.6/site-packages/telethon/telegram_client.py", line 1680, in _get_entity_from_string
    'Cannot turn "{}" into any entity (user or chat)'.format(string)
TypeError: Cannot turn "+79291101517" into any entity (user or chat)

My suspicion is that CreateChatRequest only works for my PeerUsers, i.e. using non-peer phones is prohibited in this method.

So the question is, how do I add somebody to a group chat if he is not one of my contacts?

According to the telegram document:

You can add your contacts, or use search by username.

So you can follow the steps in Telethon :

Add user to contact
Add a contact to the group
delete Contact(optional)

for example, you can use this code :

from telethon import TelegramClient
from telethon.tl.functions.messages import AddChatUserRequest
from telethon.tl.types import InputPhoneContact
from telethon.tl.functions.contacts import ImportContactsRequest

api_id = XXXXXX
api_hash = 'XXXXXXXXXXXXXXXXXXXXXXXX'
phone_number = '+98XXXXXXXXXX'
################################################
group_id = 263549607 
guest_phone_number=XXXXXXXXXXXX
################################################

client = TelegramClient('session_name',
                    api_id,
                    api_hash)

assert client.connect()
if not client.is_user_authorized():
client.send_code_request(phone_number)
me = client.sign_in(phone_number, input('Enter code: '))

# ---------------------------------------
# add user to contact
contact = InputPhoneContact(client_id=0, phone=guest_phone_number, first_name="custom_first_name", last_name="custom_last_name")
result = client.invoke(ImportContactsRequest([contact]))
# ---------------------------------------
# add contact to your group
client(AddChatUserRequest(user_id=result.users[0], fwd_limit=0, chat_id=group_id))
# ---------------------------------------
# remote contact

I used ‍Telethon V0.19, but the previous versions are pretty much the same
