Possible to bind Oculus Rift S pass-through function to a joystick button?

[Viking84]

As the title says, the Rift S has a great pass-through feature that allows you to see the outside world through the sensor cameras. Sadly this can only (as far as I know) be activated by double tapping the Oculus home button on the touch controller. Has anyone found a way to bind this great feature to anything else, either a keyboard combination or a joystick button press?

Probably not much help, but double tapping the Xbox button on my 360 controller also activates the passthrough view.

I wonder how I can do this on a Windows 10 computer playing Elite-game and then return to the game again?
