This method should be called within one second of receiving a [signal@Portal:XdpPortal:session-state-changed] signal with
the 'Query End' state, to acknowledge that they have handled the state change.
Possible ways to handle the state change are either to call [[email protected]_inhibit] to prevent the session from ending, or to save your state and get ready for the session to end.
