communication between bluprints

hey guys, so I’m trying to change a components visibility in blueprint A via an event in blueprint B.
I tried to do that by using a custom event but I can’t seem to find a way to call it in the other blueprint. Event Dispatcher might also be relevant here but not sure how it use it.
I’ve checked out the content examples on communication between blueprints but I wasn’t able to reconstruct it in my level so if anyone could provide instructions on this, that’d be great.

Thanks
