Support to use gamepad to go to the buttons like (add new machine and the Yes/No when exit).

Describe the solution you'd like

Support to use the gamepad (up, down, left, right or joystick) to switch between all clickable buttons.

Describe alternatives you've considered
For click "No" when exit, an existing solution is pressing "B" on the gamepad. So, an alternitives for clicking "add new machine" might be assigning a gamepad button for it.

Additional context

I am using moonlight client on Bazzite on a HTPC which has no mouse connected. It's good to use gamepad to select the machine and apps. However, when I want to add a new machine or click "No" when I want to exit, I always need to use a mouse to click the button.
