Tool tip pop-up for action button

Hi,
I have managed to get a series of blueprints working with an action button similar to using the example light switch tutorial, the player approaches a small box later to be rendered better as a button. Once they are within the collision scope of the box and press a button on the keyboard which is mapped to X at the moment the animation plays and a series of blinds rotate to close a window, i was wondering if there is a way of triggering some for of pop up on screen when in range of the button which for example would say “Press X to close” or “Press Y to open”.

Thanks
Chris
