Where should the Activate Reverb Effect node be used?

I have a reverb effect that I want to apply globally at runtime (to all sounds). I’ve tried using the “Activate Reverb Effect” node in a few different blueprints, but nothing happens. I know the reverb effect works because I can apply it to an Audio Volume that encompasses my entire level, and I then hear its effects.

But I’d like to know how to achieve this with an Activate Reverb Effect node, as otherwise the node seems to have no use. Any pointers?
