Detecting Oculus Home pressed in Unreal Engine 4.16


I am working on a project in Unreal Engine 4.16 for the Oculus Rift. I have already had to modify the engine code to detect when the user removes/puts on the headset, however I am not sure what the correct approach is for detecting when the user goes to the Oculus Rift Home menu. Can anyone point me in the right direction for making this happen?
