Make a button change opacity when hovered over with mouse and touch?

Hi everyone. I'm trying to make a button change opacity when hovered over with mouse and touch.

I want the buttons in my menu respond when hovered over with both a finger or mouse.

I can get the mouse to change the sprite/button opacity but I can't figure out how to change it back once the mouse is off the sprite/button.

I'm looking to do this with both touch and mouse.

Thanks

If you right-click and invert the event this will act as a 'mouse not hovering button' event as noted by the red cross. For hovering with touch that's not really a thing is it, you just have 'in touch' which is finger touching the button
