Can't delete google calendar integration

My google calendar integration stopped working when moving from Google OAuth forward authorization to Authentik. Figured I would create a new application credential and start from scratch. Well I can’t delete the old one while it’s in use by an integration.

No problem, I’ll just delete the integration. Except, it won’t go away.

I can disable it but deleting it in the UI does nothing. Tried restarting HA with the integration disabled and rebuilding the container.

Can I bring down the container and delete the “google.#” files in .storage?

NO.
Don’t mess in .storage, you will be restoring a backup most likely…

Good to know. How else can I delete the google calendar integration?
