How to end level after all enemies are destroyed

I had a lot of trouble figuring out where to put things so I put it all in both the game instance blueprint as well as the enemy character blueprint. It casts to the game instance and everything seems to work regardless, which is why I assume the primary problem is the fact that I don’t have the ReduceEnemyCount event set up to actually do anything. It’s just a a custom event renamed as it is in Spiris’ image, but I didn’t know what to do with it/how to use it. Also, for simplicities sake, I currently just have it set to open my menu instead of using Spiris’ end level stuff
