Research: open calendar/contact directly from unified search

Is it possible to open a calendar/contact from unified search local on device?

Idea

• there must be an unique id
• "just" open this via intent on Android
  • either it works
  • or it fails with correct error message

@miaulalala as you are an expert on calendar. Do we have a unique id, which unified search could send, and Android then can use to view this event?

yes, calendar events / vcards have a unique id (UID):

See for example in the widgets: https://github.com/nextcloud/calendar/blob/babc444245f6e6cef2fd1a88773532074c9cad0e/lib/Dashboard/CalendarWidget.php#L176
