Is there a way to 'Remove' or 'Delete' the Branded App?

Is there a way to completely remove the Branded App from a Wix site?

We have cancelled the subscription for it, but all this really did was turn off auto-renew. The app is still active and working because there are five months left on the subscription for it.

We have looked everywhere for a way to flat out disable/delete/remove it, but for the life of us, we can’t find a way to do it. It feels like we might be missing something obvious here.
