Hello!
We’ve nearly got our game rated as Supported for the Steam Deck, without access to an actual unit.
However we’re now hung up on a simple problem, the STEAM button apparently reports as a Keyboard key when pressed, which makes our UI show keyboard instead of Gamepad glyphs at an inappropriate time (which notches you down to Playable rating).
If someone who has access to a unit could tell us what key UE4 reports as being pressed when you do it, I would be immensely grateful
