How can I get wave height in BP?

The UE4.26 water plugin allows us to access a node called ‘calculate gerstner waves’ for materials. But I fail to see an equivalent for Blueprints.

Interesting, I didn’t know it was possible to get waves in materials, can the material be changed based on it? Like wet sand, dry sand?
And did you manage to find it? I’m having the same problem with water plugin, for swimming I’m using capsule collision with water but it doesn’t collide with the water itself but an imaginary plane, how do I get access to the waves offset? My post:
