This feature is available on Windows PCs and will be accessible from the in-game menu or, for keyboard players, by pressing the “SHIFT +F1” shortcut on your keyboard.
Playstation trophies and steam achievements are two different platforms. Why would playstation trophies be tied to your steam account?
