To keep your account safe, Google blocked this access.

I tried to run the app, as per the instructions, and got:

Authorization required. This project requires your permission to access your data.

I authorised it and got the error:

This app tried to access sensitive info in your Google Account. To keep your account safe, Google blocked this access.

I'm using the new interface on a personal GMail account.

Any idea what's going on?

Ah, looks like it is a general problem unrelated to this app https://issuetracker.google.com/issues/181220763?pli=1
