How to fix TwitchNotificationsApi code?

Question

Python

I wanted to implement a bot to send a notification about the start of the broadcast to twitch in the discord, but at the end such errors popped up! I honestly don't know how to solve this!
Mistake:

Traceback (most recent call last):
  File "D:/Flow/bot.py", line 17, in <module>
    twitch = Twitch(client_id, client_secret)
  File "D:\lib\site-packages\twitchAPI\twitch.py", line 168, in __init__
    self.authenticate_app(target_app_auth_scope if target_app_auth_scope is not None else [])
  File "D:\lib\site-packages\twitchAPI\twitch.py", line 430, in authenticate_app
    self.__generate_app_token()
  File "D:\lib\site-packages\twitchAPI\twitch.py", line 413, in __generate_app_token
    raise TwitchAuthorizationException(f'Authentication failed with code {result.status_code} ({result.text})')
twitchAPI.types.TwitchAuthorizationException: Authentication failed with code 400 ({"status":400,"message":"invalid client"}
)

Process finished with exit code 1

The code itself:
