Add Screenshot Functionality

Please add screenshot functionality to EA App's overlay. The overlay doesn't even seem to have any use at the moment, and the only other way to take screenshots if a particular game doesn't have a built-in screenshot function is to use GeForce Experience's ALT+F1 keybind (which can trigger in-game actions due to the ALT key). Windows's built-in screenshot function with the PrintScreen key doesn't seem to be a viable alternative as it just results in a solid black image.
