OpenXR Get MotionController Types / HMD Type

Hey guys.
I´m currently trying to figure out what kind of Motion Controllers / HMD the Player is using so I can adjust the shown Meshes etc.

Using OculusVR / SteamVR there were some C++ / BP Functions helping with that but for OpenXR I can´t seem to find anything useful.

Has anybody got an idea where to retrieve these information?

By the way, I´m using the UE4 4.27 Preview 2 at the moment.
As it says that with 4.27 OpenXR now is production ready I wanted to make the move there.
