Can not map controller

I have a Google Pixel 2 XL phone and a Steelseries Stratus XL controller. I am able to connect the controller to my phone via Bluetooth and I am able to control phone and other games with the Stratus XL.  However I cannot map the controller via Minecraft settings.  I can only move forwards, backwards, strafe left and strafe right with my controller using the d-pad and left joystick.
