How to parse users with bio from Telegram group

from telethon import TelegramClient
from collections import namedtuple
from telethon.tl.functions.users import GetFullUserRequest

api_id = int()
api_hash = ''
phone = ''
limit = 10000


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


async def main():
    full = await client(GetFullUserRequest('username'))
    bio = full.full_user.about
    print(bio)
with client:
    client.loop.run_until_complete(main())

here is the code that finds the bio by username, but I need it by id and in addition to this I can't ask for groups in any way There are many answers in SO, but they are already on the old version and now the bio is not parsing In general

• Find bio by id
• Parsing users from groups (if possible, with bio)

Is this even possible now ??
