Use raycast (center of screen) instead Mouse in UMG

Hi, my porpouse is not use the mouse to select, hover, etc… in UMG, I want to control it with the crosshair, so if is in the middle of the screen, it is the active widget. Could be possible?. A fake and poor idea could be fixing the position of the mouse cursor always in the middle of the screen, I haven’t already get it but probably a better way is viable…
