Custom Guard Audio

Hi, I am making a horror theme map. I have custom monsters made through Custom Guard Retargeting and I want to add unique sounds to the Guards so it adds more atmosphere to the map. But I couldn’t find anything helpful. I found only this: Stronghold 05 Set Up Audio and Visual Effects in Unreal Editor for Fortnite | Unreal Editor for Fortnite Documentation | Epic Developer Community, but the Verse code here is not working. Is it even possible?
