Flatpak: How to share CalDAV events with other apps/system?
As noted in #633 (closed) and #907 (closed), the Flatpak version of Evolution does not integrate into the rest of the system. For example, Gnome Calendar does not show any CalDAV events from Evolution. This is due to the sandbox environment of the flatpak version.
Fedora heavily encourages the use of flatpaks. On Fedora Silverblue, flatpaks are pretty much the only way to install applications without modifying the (immutable) base system.
Is there a way to make the flatpak version work with the rest of the OS, e.g. by modifying flatpak permissions?
