Gamepad change buttons, use in editor

Hello, I’m desperate to assign my gamepad to UE4 buttons. It is recognized as a gamepad, and works as usual. But I have to reassign the keys to use it as a WASD replacement. I have long searched here in the forum, but find nothing.
Just assign new functions to the buttons. Can someone help me?
All plugins and blueprints I found relate to games, but I want to use the controller in the editor itself.
Thank you for tips!
