Call a Function in level Blueprint from an Actor

I have a probably quite simple problem. I have started another minigame. I that you have to walk over a tile and find a button. The Tile is an Random generated actor. If you click the Button the Actor should call a function within the level Blueprint where all the Tiles are stored and spawn a new tile with parameters given from the actor. But i have no idea how to call a function thats inside of a level blueprint from an actor blueprint.


You can do this using an Event Dispatch, take a look here:

You can also reference the Blueprint_HUD Content Example for how the OnPickedUp event is called via Event Dispatch.

This should give you an idea on how to approach it.
