Covering Calendars possible after loss of hardware?

Hej guys

I lost my Nextcloud hardware due to hardware defects. I backed up all except my calendars. There is no way to access on hardware itself. Lost.

I use Google calendar on my mobile device. I still can see all the calendars and their data in it which I have implemented with DAVx. Now I try to find a way to export them.

I did not find the option to export them from Google Calendar app nor DAVx.

Does anyone know a solution to keep these data? Maybe other apps which can read current data from Google app or DAVx?

Kind regards

Should be possible to export the Google calenders.

I would ask at the Google Calendar Community.
