Is there some way to extend the Calendar in that way, that we could have a small Trashbin, where deleted Objects from Calendar and Contacts are stored for a defined period of time?
Reason fo this is: I have some users where Calendar Entrys disappear mystically from the Calendar (not from Nextcloud, they disappear in Outlook.com and Google). With such a feature, we could restore such Events. Maybe there is a way to find out what deletes this events. Either a Calendar App, a Sync Adapter or anything else.
