Organ / Keyboard Particularities

I understand from someone else on the forum that it is already possible to integrate Dorico & the pipe organ “VST” program Hauptwerk. Has anyone done this yet and if so, can you describe how to get them to work together? While I’m well versed in Hauptwerk and comfortably versed in Dorico, I am totally at a loss for how to configure them together. This is simply not anything I’ve ever done.
