CommonUI EnhancedInput Generic Click and Back keybinds absolutely refuse to work. Any ideas?

I’m stumped. I cannot for the life of me get the enhanced input generic click and back keybinds to work at all. They refuse to do anything.

Am I just misunderstanding the point of these? As I understand it I should be able to press the enhanced input key (e.g. A) to activate a button, but it absolutely does not work.

Only Space and Enter (hardcoded keybinds) work if I’ve set “Common Button Accept Key Handling” to “Trigger Click” in Settings > Common UI Framework.

So am I misunderstanding something here? I’ve followed the tutorial a dozen times. Including in a clean project. In the clean project as soon as I set “Common Button Accept Key Handling” to “Never” then I can’t activate buttons with keyboard navigation anymore.

I’ve also tried adding the Generic Click to “Triggering Enhanced Input Action” for a button. It again, does nothing. Despite following the tutorial exactly as provided.

I take it CommonUI after all these years still does not let you add new navigation keys? FNavigationConfig is still required?
