How to create sections that tell the controls of a game

I am trying to create a 2d metroidvania type game and I would like to create a way to explain the controls for moving left and right at the beginning of the game at the player spawn. I tried doing it based on character overlaps and boxes but it ended up not showing up while the character was overlapping with the entity that contained the message and when the character stopped overlapping, the message would pop up. If anybody could help me do this that would be great.

It seems you used the wrong overlap event. There is one for BeginOverlap and one for EndOverlap.
