Adding Books via Nautilus or CLI inteface fails with Flatpak.

[ghost]

Foliate's flatpak appears to be broken when trying to drag and drop a file from Nautilus. Also --add from the command line fails in a similar fashion. Non-flatpak version of the application works when dragging and dropping books. This is on Fedora 33.

Yeah, for Flatpak, it can't access the files directly because it's sandboxed. The portal for drag and drop seems be supported by GTK 4 but not GTK 3. See flatpak/xdg-desktop-portal#99.

I don't think this is a bug. One should use the --file-forwarding option of the flatpak command.

As of v3.0, there's no --add option or drag and drop, but those are separate issues.
