Cannot find the where the steam input plugin is located

Hello I’m trying to configure the steam controller plugin, but i cannot find where is located in the unreal engine folder.
can someone please help?

Engine\Plugins\Runtime\Steam\SteamController

But you only will find defaults there, the saved data lands somewhere in Saved/Config folder, wither in project directory. You also should set defaults in Config forder of your project, it will override plugin defaults
