org.freedesktop.portal.Flatpak:
@short_description: Flatpak portal
The flatpak portal exposes some interactions with flatpak on the
host to the sandbox. For example, it allows you to restart the
applications or start a more sandboxed instance.
The D-Bus interface for the document portal is available under the
bus name org.freedesktop.portal.Flatpak and the object path
/org/freedesktop/portal/Flatpak.
This documentation describes version 3 of this interface.

Spawn:

@handle: Object path for the #org.freedesktop.portal.Flatpak.UpdateMonitor object
Creates an update monitor object that will emit
signals when an update for the caller becomes
available, and can be used to install it.
The handle will be of the form /org/freedesktop/portal/Flatpak/update_monitor/SENDER/TOKEN,
where SENDER is the caller's unique name, with the initial ':' removed and
all '.' replaced by '_', and TOKEN is a unique token that the caller can optionally provide
with the 'handle_token' key in the options vardict.
Currently, no other options are accepted.
This was added in version 2 of this interface (available from flatpak 1.5.0 and later).
