4.14 Grip cap touch missing

Hi,
So I couldn’t find another thread about this. I found the capTouch function for pointing and trigger which just reads the same button (trigger) just flipped values. I cannot find anything for the grip button, the one you use with your middle finger.

I am just trying to find weather the middle finger is on the button or not. Anyone know what it’s named?

Thanks
Russ

Yeah, that button doesn’t have captouch. I was a bit disappointed to find out.
