Hello,

all the distrobox-export-ed applications on Aeon (MicroOS), although being
visible/searchable on the desktop, can't be selected as "default" apps for the
GNOME DE.

For instance, Claws-mail flatpak does not contain "fancy" plugin, so I had to
install it and exported, but then it's viable option for "default" mail client.

Similarly to Firefox - my eID could not work with flatpak version, so I have to
keep twp versions – one which can understand e.g. links from other flatpak
applications like Element and another for eID feature.

I know that Aeon/MicroOS is a new thing, but I like it a lot. Still, wondering
whether the above issues are due to Flatpak packaging, distrobox limitations or
Aeon/MicroOS bugs?
