xPilot and PilotEdge PTT compatibility

I saw this thread that discusses using the Contact ATC Override feature to allow both xPilot and PilotEdge clients to use the same PTT button. I think that this thread is from before the release of the new client. I note that the plugin still has the “Contact ATC Override” option, but I can’t get Contact ATC to light up my PTT in xPilot. Does this still work?
