Hi guys! So, I have Proton Mail, and this also gives me the Calendar. I love that I have a encrypted private calendar, but it bothers me that it doesn’t play well with any other app, as it’s not officially a “calendar” to Android. This bothers me, because I use GrapheneOS, with mostly no Google services, and I'd like my Gadgetbridge-connected smartwatch to be able to display calendar events, since they're not being shared with anyone else. But I can't, because Proton Calendar isn't really an Android Calendar. There’s a way in Proton to permanently share a link to your private calendar. In effect, it’s an up-to-date .ics file, that I believe needs to be checked/downloaded every time there’s an update. Is there a way to update this in Proton? Alternatively, I wouldn’t mind creating some caldav system that imported this, but not sure if there’s already any guide for it?

Thanks so much!
