C++ Gamepad UI Navigation - Can't "hover" on buttons, but am able to select and navigate.

I’ve been round the houses trying to find a solution to this and just can’t seem to find it.

I’m building out a new project and want to allow the player controller to access the pause menu via the gamepad.

Currently the following code allows me to open and close the pause menu, I can also navigate (up, down, left, right) and select using the D pad and Bottom face key.

I have two questions:

  1. Why do the buttons not enter “hovered” state when selecting them with gamepad, and how can I fix this?

  2. I have not actually created input actions for menu navigation, this seems to automatically happen whenever I open the pause menu widget. This leads me to believe that my code is having little impact on the menu navigation system, and if so, is there a better way for me to play with the functionality rather than from the player controller?

    if (UEnhancedInputComponent* EnhancedInputComponent = Cast<UEnhancedInputComponent>(InputComponent))
