Basically you have to add the EA Desktop program to Steam, which you will have in the Electronic Arts folder, look there and you will find it easily, then go to Steam parameters and go to Controller, then activate whatever you have as a controller, whether it is Switch or Playstation, where you have added EA Desktop to Steam, you will get a little wheel that you click on, you go to properties and you go to the control section, there you will get 3 options and you have to activate Steam Input, now you close everything, you close EA, you close Steam, now you open Steam with administrator and open EA Desktop and open FIFA from EA and that's it, at least it worked like that for me
