End of legacy OAuth 2.0 grant types -- Client Credentials

My question concerns this article .

We have a specially developed automation that runs on our server and deletes old chats. This authorizes itself in the live chat API with the client credentials flow where the client ID and the client secret are exchanged for an access token.

As the API does not accept API tokens, we have no other option.

The article does not mention the Client Credentials Flow, so I want to make sure that it can still be used in the future.
