Error 403 last step google nest thermostat / HA

I reset my nest thermostat to factory setting, and not it isn’t visible anymore in HA.

Dit the steps from Google Nest - Home Assistant

After the final step “Link Google Account” I don’t get the screen where you have to click advanced. Ik get this message

home-assistant.io has not completed the Google verification process. The app is currently being tested, and can only be accessed by developer-approved testers. If you think you should have access, contact the developer.

If you are a developer of home-assistant.io, see error details.

Error 403: access_denied

I had hoped to get the message show below so I can click “advanced” but don’t get this message


SOLVED

Needed to add myself as a test user.
