Tesla Fleet Integration, start from scratch?

I got an error installing this integration, where it says it needs to open an external site to continue

Something went wrong. Try again later

The 'redirect_uri' supplied is not registered for this 'client_id'.

I want to start over where you specify the client ID, secret, etc. But every time I try to add the integration again it opens the external web page. How can I wipe the current settings and try again? I have a different client ID that I want to use.

Found it, thanks to AI.

In HA, go to device & settings. Click the 3 dots menu. Delete the TeslaAuth item.

Done.
