Sync only occurs when restarting Thunderbird. Manually sync also does not work.
Thunderbird Supernova version 115.7.0 (64-bits), add-on version 115.0.2.
As a workaround I use the "Open Google Calendar" add-on (opens Google Calendar in a new tab).

This review is for a previous version of the add-on (115.0.2).
