With postmarketOS edge Sxmo I managed to get the (Alpine package) of Snapshot working on my PinePhone Pro. I've tried to get the flatpak of Decoder to work ( https://flathub.org/apps/com.belmoussaoui.Decoder ) ... but I fail at portal (or dbus?) setup

'Failed to read portal settings: GDBus.Error org.freedesktop.DBus.Error.UnknownMethod: No such interface "org.freedesktop.portal.Settings" on object at path /org/freedesktop/portal/desktop'

and can't seem to find helpful documentation.

@linmob also i assume that sxmo does not provide anything that provides the freedesktop.Portal.Settings interface since it is a lightweight environment? i'm not familiar with "mobile linux" but on the desktop side i would've assumed that with something like i3. Might want to get a D-Bus debugger running like D-feet or D-spy and look at what stuff is available.
