Help with Xbox support

Hello. I’m currently trying to make everything in my game Xbox support but how do I make it where if they JoyStick up or down or DPad up or down or right to left it goes to different TextButtons? The only way they can do it is if they press the tiny left button under the Xbox logo

I am afraid you will have to develop Your own system. How to do it will heavily depend on Your current GUI setup and the way you handle button presses. This is not an easy task, an I suggest to do it only for the frequently used buttons that are essential to Your gameplay.
