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).

Ta opinia jest o wcześniejszej wersji dodatku (115.0.2).
