MMM-Calender with share of mailbox.org calender

[azuettel]

I’m changing from gmail to mailbox.org and I’d like to add my calender like I did with gmail. Unfortunately from my new calender provicer mailbox.org I can’t get a .ics share, the only thing I get is a link looking like this https://share.mailbox.org/ajax/share/… or the CalDAV link looking like this https://dav.mailbox.org/caldav/… Is there a way to feed my MMM-Calender (or maybe a different module)?
