Unable to make platforms buoyant - UEFN

Hi, I’m trying to make a platform level where players move across platform that are floating in water. I have tried a bunch of things such as custom scripts on Verse, but it doesn’t seem to work.

I have seen that it is possible thanks to this article at around min 38:15, Chaos Physics in LEGO® Fortnite: Building A Fully Interactive Sandbox Experience | GDC 2024 | Talks and demos however I don’t know how to get this type of behaviour in floor like props. I even tried switching to a LEGO map template to see if that was the issue but no results.

Anyone knows whether this is possible?

Appreciate the help.
