AttributeError: 'TelegramClient' object has no attribute '_event_builders'

I'm using Telethon v2 and I'm getting this exception:

Code

from telethon import TelegramClient
from telethon.events import NewMessage

api_id = 000
api_hash = '000'
channel_id = -100000

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

@client.on(NewMessage(channel_id))
async def callback(event):
    print(event)

Traceback

Also, somehow, I needed to install markdown-it-py by myself cause it didn't consider it as a requirement, so maybe something was wrong with the way I installed Telethon v2?

v2 is still in the works and pretty much not ready for use yet (it's missing a few changes and then a lot of testing and docs updates).

So the update for restricted contect channels is irrelevant at the moment? Cause this is why I tried to update to v2

Closing since v2 is not yet ready for public use, and this error should not be present in the currently-published v1.25 available from PyPi.
