PhotonSync events

I'm using PhotonSync to send a list of items and I would like to clear the list when the PhotonSync screen is closed. Is there a event handler that I can tie into?

Unfortunately there is not currently an event handler for this

New information:

The JourneyApps runtime has automatically wrapped the photonsync calls in promises, so this should actually be possible without an event handler.

    dialog("Transmit completed.");

In the above, the dialog - or in your case clearing the list - will execute after the .transmit() window has been closed.
