The current implementation indeed generates share links only when the event is shared to other attendees. I thought Evolution didn't show such attachments.

A proper implementation of https://github.com/nextcloud/calendar/issues/5001 should fix this.

Zocker1999NET commented 3 months ago

If I understand #5001 and the referred RFC 5001 correctly, then this would only really enable syncing & sharing attachments with clients logged in & using CalDAV. In case nothing else is implemented additionally, this would still hinder access of users not signed in at all. And I would also like to have a way to share a calendar & its attachments with a public user base (i.e. not signed in).
