Easy way to remap keyboard and mouse to controller

I can use whatever controller. I have Xbox one or Dualsense/Dualsense Edge controllers.. I can't figure out an easy way to remap to them though.. id prefer to keep it free but would pay a little to make the issue go away.. Convenience is my biggest goal here

I tried this before and it turned out terrible, I suggest getting a refund from your cheat providor and use interwebs which has controller support.

Windows ds4 free and best option for sure

Why would you want to do that?
Terrible idea to start with

In the past I am using Rewasd with keyboard and mouse to get the controller aim assist. It works but it was very slowly when I’m moving the mouse. You can setup this but takes many time.
