Calendar does not work with Google account

## What Happened
I have a google account with two factor enabled. I went in an created an app-specific password for mail, which worked fine with the Mail app. I also created an app-specific password for calendar and attempted to create a CalDAV account, but that does not work.

I've attempted many URL variants based on what I could find online for the Server URL input:
https://www.google.com/calendar/dav/username@gmail.com/user/
https://www.google.com/calendar/dav/username%40gmail.com/user/
https://apidata.googleusercontent.com/caldav/v2/username@gmail.com/events
https://apidata.googleusercontent.com/caldav/v2/username%40gmail.com/events

For the User Name field I've attempted a few variants as well:
username@gmail.com
username%40gmail.com
username

And for the Password I've tried the account password (fails saying I need an app specific password) and then the app specific password.

The error I receive looks like this:


## Expected Behavior
I would expect the calendar authentication to work and list calendar events.

I would also expect an official guide containing common configurations for the Calendar app, or even a wizard containing popular email account types (pretty sure this existed in previous releases).

## Platform Information
Most recent Odin ISO download with all updates.
