Flatpak Nautilus can't eject device held by xdg-desktop-portal
Nautilus 3.35 Flatpak nightly
Currently ejecting an USB device shows a warning that the xdg-desktop-portal PID is holding it, which makes "Force Eject" mandatory in a somewhat confusing way. I think the x-d-p lock on devices could be handled more cleanly, but I do not know enough about how xdg works to suggest an alternative.
