Why is the code not running correctly?

Question

Python

There is a code:

from telethon import TelegramClient, sync


api_id = 'мой id'
api_hash = 'мой хэш'
username = 'мой номер'

client = TelegramClient(username, api_id, api_hash).start()

channels = {d.entity.username: d.entity
            for d in client.get_dialogs()
            if d.is_channel}

for u in client.get_participants(channels['test'], limit=10):
    print(u.id, u.first_name, u.last_name, u.username)

I have channels and groups. I would like to get all users of a group named test . I looked at the channels list and there were only channels that I subscribed to. The task is to get the users of the group named test, if you are not an administrator.

Answer 1

Maybe you do not see the groups, because you yourself discard them?)
Please pay attention to if d.is_channel

channels = {
            d.entity.username: d.entity
            for d in client.get_dialogs()
                    if d.is_channel
}
