Add event id to google calendar events to update events

I’m using an automation to add events to google calendar. Now it’s not possible to update an event in Google Calendar because of the missing event id. It would be nice to add this to the HA integration.

The case now:
add event: test1 - 10.00 till 11.00
updatet event: test1 - 10.30 till 11.00
result: 2 seperate calendar events

wanted result: 1 calendar event (test1 - 10.30 till 11.00)

This is the release notes for the current release candidate of HA.
It has some mentioning on calendars.
