An event is delivered to the RxM provider, but that is not exposed.  This is an implementation detail of how rxm works in conjunction with a MSG provider.  Not all RDM providers would have a similar restriction.  More native ones probably wouldn't.

Off the top of my head, I'm not sure what a good solution would be for avoiding the first message setup latency, particularly one that wouldn't make things worse on the app.
