'Right Touch Oculus Home Button' handling

Hi!
There is an Oculus requirement when submitting a build for Rift that is the 'Oculus Home Button Re-Orient' feature. There are several button combinations that can 're-orient' the playing area, but one of them is described as follows:

'Push down on BOTH the Left Touch Menu Button and Right Touch Oculus Home Button'.

I can handle the 'Left Touch Menu Button' with no problem, but, as far as I know, the 'Right Touch Oculus Home Button' is a reserved one in unreal, and its input is not exposed, or can not be handled. In fact, the default behavior when pressing that button, is to display the 'Oculus Universal Menu', which is a perfect default behaviour, but I can`t find a way to intercept it...

Does anyone know how to deal with that problem? Is there any way to intercept the 'Right Touch Oculus Home Button' input?

Thanks in advance.

Iñaki.
