No GetDevicePoses or RecenterTrackingOrigin in UOculusFunctionLibrary

Hi, I am trying to port the native PC SDK demo app (TinyRoom) to Unreal (C++).  I did find UOculusFunctionLibrary (https://docs.unrealengine.com/en-US/API/Plugins/OculusHMD/UOculusFunctionLibrary/index.html) but it doesn't provide a means to recenter the HMD, nor get the pose velocity/acceleration available in the over_GetDevicePoses.  Anybody know if there is another Unreal C++ class I should be looking for?  Thank you for your consideration.
