War robots+xbox360 controller on Android? Maybe add support?

So I got a usb type C to regular usb adaptor for my Pixel C tablet. Plugged in my xbox360 pc controller & the tablet sees it. I can use it in real racing 3 & couple other games. In war robots, it also walks the robot & turns the  turrent. I just can't fire any weapons. Is there something I need to do so it works fully? Or does the game just not support it?

If not I'd like to request for the developers to add support for it please?

I know you can make an xbox360 work on the Menu emulator on a PC. But that's after custom mapping the controls etc etc..
