Subscription to calendars

Is it possible to ad a subscription calendar?
In my case it is a calendar for recipe keeper:

I have also a subscription fcalendar or the school of my son.

I have it in my own Icloud, but with the caldav calendar it did’nt work because it is a subscription.

Use the remote calendar integration.

Awesome. Thanks!
