Mac xbox controller detect trigger input

Hey, I’ve set up my xbox controller to work with my mac using the tattie bogle driver and I’m using this page as a reference for the input: (scroll down to bottom for mac version)
The only thing that I can’t get to work is the triggers. Heres a picture of my input for running: what do I need to do to get it to recognise the left trigger?

What you need to do for getting the triggers to work is treating them like the analog sticks.
You need to change the value for “Type” to “Joystick Axis”.

From here I was a little stuck, since I didn’t get any values from it. That was because I listened for input if it was a button. Instead treat it like an axis as one should. You can check the output ranges with this code. They go from -1 to 1.

print (Input.GetAxis("Run"));
