How can I use an Xbox Gamepad to control chaos vehicle?

I finished my keyboard setting in project setting tab and chaos vehicle blueprint, and it works well in play mod.
But I want to control the car with gamepad for better control.
My PC is connected with the gamepad and in third person starter project I can use gamepad to control the mannequin character.
But it isn’t working in my chaos vehicle gameplaymod.
I think I should try other way in event graph page but I couldn’t find solutions.

How should I make a setting to use xbox gamepad for a chaos vehicle plugin?
