Does Companion work with UltraStudio Mini 4K?

I do not see anything for the UltraStudio Mini 4K (or DesktopMedia) in the companion listings under Black Magic Design. How do you trigger a stinger in the USM 4K (DesktopMedia), so that I can cover a transition with it?

oooops, the software for the UMS 4K is called Media Express.
