Python VK_Api Why can't login with community permissions?

Question

Python

Everything works for the user, but not with community rights. Even though this code worked before. Not now. What's wrong?

import vk_api

vk = vk_api.VkApi(token='блаблатокенбла')
vk.auth()

vk.method('messages.send', {'user_id': 'блаюзер', 'message': 'сообщениебла'})

Traceback (most recent call last):
  File "main.py", line 4, in <module>
    vk.auth()
  File "/usr/local/lib/python3.6/site-packages/vk_api/vk_api.py", line 143, in auth
    raise LoginRequired('Login is required to auth')
vk_api.exceptions.LoginRequired: Login is required to auth

a token from a group, but if I add a username and password from a user, then he simply enters the user and performs actions on his behalf, and not on the community.

Answer 1

vk.auth()- only needed when authorizing a user
When authorizing with group access rights - no

Answer 2

I know that it is very relevant, but - vk._auth_token()a function for authorizing the community by token
