Here is the updated code. replace appid, apphash and username

with TelegramClient('session.session', <app-id>,<app-hash>') as client:
result = client(functions.contacts.ResolveUsernameRequest(
    username=<username>
))
print(result.stringify())

There are 4 ways to get access hash:

  1. From a Group
  2. From username
  3. From contact list
  4. From chats message

So, if you have id only, there is no way to get access hash

In order to find channel access_hash, you should resolve channel username. Original MTProto method contacts.resolveUsername#f93ccba3 gets @username and returns channel info including access_hash.

In telethon you need to invoke ResolveUsernameRequest to call the above original MTProto method. You may use this code to resolve username to access_hash:

client = TelegramClient(session_file, api_id=00000, api_hash='XXXXX')
client.connect()
response = client.invoke(ResolveUsernameRequest("your_channel_id"))
print(response.chats[0].access_hash)
client.disconnect()
