Here is the URL of the Looker link created through my Google Cloud console: https://4cebee34-9182-4631-89cd-8b9b0aa9ef99.looker.app/
Once clicked, getting this message:
Access blocked: authorisation error
The OAuth client was not found.
If you are a developer of this app, see error details.
Error 401: invalid_client
Is it due to the fact that subscription for Google Workspace associated with email@example.com has expired. However, I could access Google Cloud console with this id (firstname.lastname@example.org) that has also startup credits remaining.
