Synchronizing google contacts with Thunderbird / 2023-03-15

Ages ago I added a way to get access to my google contacts as a thunderbird address book. But on installation of thunderbird on a new laptop I couldn't find a simple answer to "how did I do that again?!?".

With access to the old laptop I was able to reconstruct my steps, so I'll note them here:

• Install cardbook as add-on in Thunderbird
• Go to this add-in in the Thunderbird userinterface
• From the top left 'hamburger' menu, select 'Address book', 'New address book'
• A window pops up asking 'Address book location', select 'Remote'
• The next window asks 'type of your address book' and gives google as default selection
• As username enter the standard address used for your google account. This doesn't have to end in @gmail.com.
• After entering the address, click 'Validate' and a window pops up with a minimal browser to log into your google account. Do this.
• After logging in the browser window will ask for permission for Cardbook to access your google contacts.
• After selecting a colour for this new address book you can use it.
• In the process google will probably send you alerts about this new login and permission.

And now my contacts are synchronized between android phone, google contacts web interface and thunderbird!
