Hand tracking system gestures, possible solution?

Hi!
I am currently developing for unreal and I find the hand tracking will be perfect for my use. The issue is that of all the gestures we can use, the thumb and index pinch is by far the most accessible and easy gesture to use and for the headset to recognize accurately, and that is a gesture that is system reserved. Even if I try to close my fist and then pinch it still sometimes recognizes the pinch as a system gesture instead. It would be unreasonable to request access to system gesture behavior for obvious reasons as apps and programs shouldn't have that access to begin with. 

I'm not sure what would be the best solution here, as I'm probably not alone in feeling a bit hamstrung trying to use such an awesome feature as hand tracking but being constantly thrown to the menu while using it. 

Some proposed solutions:

-Make it possible to change the behavior in the headset menu so you would have to hold the palm up pinch for X amount of time before triggering the system menu. 1 sec, 2 sec, 5 sec, 10 sec for instance. Maybe with a ring closing around the meta icon to indicate how far away from opening the menu you are.

-Make it possible to change the behavior from thumb and index pinch to something less used, like thumb and pinky pinch, or requiring both hands to do the system pinch. 

-Personally I would love to be able to relegate that system menu to the power button, so that if you are within an application, the power button would bring up the system menu. (Then long press to switch off the headset)

Any feedback or possible workarounds would be much appreciated.

Best regards
