VKB-SIM

Just installed a VKB STECS Throttle System Mk.II - Standard. on MSFS 2020. I can’t get any key on the throttle to bind to the reverse thrust. I mostly fly TBM 930 and the Honda jet. My reverse thrust was working on the prior throttle. I did everything recommended. Your expert help is needed.
Any thoughts would be appreciated.

What exactly doesn't work?
I assigned a button in the game (at my discretion, you can use it as a toggle switch so you don't have to hold it down), everything works.
We pressed the button, the reverse turned on, but we still move the rudder as we moved it away from us, but in the plane it will move towards us.
