Custom event from sublevel into main level

I have 2 levels. Level_A with is main level and Level_B with is sub-level. In Level_A i’m imported Level_B with levels tools and change streaming method on always loaded. In level blueprints Level_B has custom event “cs_level_b”. How i can get this custom event in level blueprints in my main level, Level_A?
Thank you!

You can do it with a lot of messing about, but it’s much easier to just put blueprint actors in the levels, they can just talk to each other.

Or, you can use the game instance. This is available everywhere. Put the custom event in the game instance instead of the level BP.
