Controller Mapping on Android

Hello everyone! So in this moment of social distancing I decided to try mobile gaming, in particular WoT Blitz. After 4 games I found out that using the touch screen is not for me and I wanted to try using a controller. I dug out a PC/PS3 compatible controller and connected it to my phone (Android 9). In the OS it works perfectly but in WoT I can’t fire. Does anyone knows if there exists an app that won’t try to steal all my data, doesen’t requires root and can emulate screen touch through a controller? Thanks!
