iCalendar binding suitable for Nextcloud calendar?

I have the idea that rules fire according to the status of my nextcloud calendar. I wonder if this (caldav-)calendar can be accessed via the icalendar binding.
Are there any experiences?

Nextcloud supports the iCal standard for sharing calendars.

Great! I’ll give it a try. Thank you for the answer!
