QA Instructions

If you already have a valid HF token saved, you should see the new UI where the token is displayed in a disabled input field (it's not your actual token, it's 37 letter a, same length as a real token).

Try resetting, setting an invalid token and setting a valid token.

🚨 The Reset button uses the HF Hub to reset the token. This permanently deletes the token from the HF hub cache. You'll need to go back to HF to retrieve it or make a new one if you don't have it saved somewhere else. 🚨
