This is what worked for me. I’ve also used the SpringArm component as Rudy suggested, but the rest of the logic is different:
Besides using EnablePlayerCameraManagerFollowHmd of OculusLibrary you also must Enable FollowHmdOrientation on CameraManager (these two actions are different, one modifies the PlayerCameraManager and another one sets flags for the Oculus plugin; I know, ugly, but it was a temporary solution until the proper one is introduced by Epic).
After all of this done, you can use GetActorLocation/Rotation from the PlayerCameraManager to set the location/rotation on the SpringArm component.
