None of the share options in the GUI do what I need, and I cant find anything in the documentation on how to do this.
I need to create a single URL that allows people who do not have nextcloud accounts to subscribe to a public calander within whatever calander app they allready use (not just download all the events in the calander currently, when they click the link it should add a subscription to their calander so they see any changes and updates made)
They dont have (and will not get) nextcloud accounts, so they cant authenticate via caldavs or whatever. And these users are not tech savy enough to do things like open settings, copy paste links, or do anything more complicated then click a link, and have the gui guide them through the rest of a very simple process.
It does not have to be one single link for every type of OS/calander app, as long as I can make a list that says:
click here to subscribe to calander with IOS
click here to subscribe to calander on android
Click here to subscribe to calander via google calander
click here to subscribe to calander with outlook
click here to subscribe to calander with thunderbird
