As we all know, Bethesda's launcher was deleted and so the integration stopped working. Unfortunately, I still have the integration visible in the game plugged in. I don't know how to remove them. In order to remove the integration, I would have to connect to it again, which is impossible. Do you have a way to do this?

I have the same problem with Wargaming integration

Not an answer to your question, but I recently found you can transfer your Bethesda games to Steam.

After that you don't really care for the integration.
