Controller Mount for R6

I bought a xim matrix for R6 that’s gonna come in tomorrow but since siege has one of the higher level MTs, I heard unless you have some sort of method it’s better to use an analog stick for movement instead of a keyboard, and then I found out you can just use the left side of your controller. But holding the controller up with one hand feels uncomfortable and saw some people had mounts for them and I’m wondering if anyone knows a semi-cheap option that I can buy. Also another quick question what should I set my lean binds to? I used QE before but on the roller I have all left side buttons + 2 paddles as well as 2 mouse side buttons.
