I'm not in a position to try ATM, I thought the same question, but could you not just use the web app and have the mobile browser post notifications as happens on the desktop version? There might be different limitations wrt delivery latency between the app and sit though, particularly when your device is in low power mode to conserve battery between periods of activity.
