Hello! I need your help, please. How can I set the reverse thrust in AAO on the Thrustmaster Warthog Throttle? I defined the thrust lever as an axis and that works very well. The reverse thrust is defined as buttons on this throttle control. Button 28 is the left and button 29 is the right thrust lever Button. I've already tried all the parameters in the Button configuration, but I can't send the signals to the simulator. I would be very grateful for help, maybe someone has already solved the problem? I'm not a programmer, so I need help from professionals. I'm talking about the MSFS2020 simulator and I've removed the bindings in the simulator. Many Thanks.
 

In the CRJ I have button 29 assigned to Decrease throttle, when I pull the throttle back and up over the detent engages max reverse thrust, pushing back forward goes back to normal forward thrust mode, works with the FBW A320 too.
