This calls out to the "snap routine file-access" helper command, which produces output compatible with "flatpak info --file-access". While this command was only introduced in snapd 2.45, the failure mode with old versions is consistent with the previous behaviour: assume the snap does not have file access.

At present, the
snap routine-file-accessreports read-write or read-only access for the following:/var/snapand~/snap.home, paths under the user's home directory excluding the~/snapdirectory and top level hidden files.removable-media, paths from removable media directories (/mnt,/media, and/run/media).These paths should all have the same meaning inside and outside the sandbox.
