Calendar stopped working with my Gmail accounts possibly due to Google's OAuth 2.0 policy.

Is there any workaround to be able to add my 6 gmail accounts again to Calendar?

Thank you

I have El Capitan on MacBook Pro Late 2008.

For Mail: Add "other account" by adding app password instead of normal password (source).

This does not add calendar, so:

For Calendar: Add CalDAV Account with app password like this (source):

The new Endpoint doesn't work.

Kind regards
