Cast to player Character happens to everyone in multiplayer

I am trying to make a jumpscare when a player gets near a monster. In this image(monster blueprint has a box collision attached) other actor return both server and clients which triggers the interface event on everyone on the server

The interface event is in the player character and it triggers a widget

Any ideas on how can i make the event happen only the overlapped character that’s close to the monster? Because when a character is overlapped everyone in the server gets the screen
