      This simple interface lets sandboxed applications query basic
      information about the location.

      This documentation describes version 1 of this interface.

        any time be closed using org.freedesktop.portal.Session::Close, or may
        at any time be closed by the portal implementation, which will be
        signalled via org.freedesktop.portal.Session::Closed.
