Use calendar app as a caldav client?

I would like to know if it’s possible to use nextcloud/calendar app as a client for another caldav server? I think I have read that it is, but I can’t find it now that I’m looking. We have another server implementation of caldav, and if we can hook into it that would be nice. Not just as ics (I see how to do that), but full read/write of remote calendar events (on other server).

Thanks

It’s not, but it would possible to fork it and make it possible.

No that’s not possible, except that you can subscribe to an read-only iCal calendar. This has already been discussed here:

or here

I would recommend to use Vdirsyncer to synchronize your calendar databases.
