How do you assign the right stick to flick stick in AntiMicroX?

[nesper8]

flick stick is a novel idea for using the right stick especially in FPS games

instead of looking towards the direction of the stick, the right stick view is locked in the x axis

for example, if you pull the right analog down, you can immediately turn 180 degrees (instantly looking back)
turning the right stick left or right would also make the character turn 90 degrees clockwise/counter clock wise towards the direction the stick is tilted

the idea is that assigning the controller's gyro for the mouse look and twitch movements and assign the right stick for quick rotations

YouTuber SolarLight has done an extensive video on this which you can check out here:
