Question How to enable SpeedTree wind in HDRP?

I have a jungle pack of speedtrees, I use HDRP/Nature/SpeedTree8 shader, it clearly has wind functionality inside the graph. I have a wind zone in the scene but it has no effect. What am I doing wrong?

I think the tree model has to have a component that copies the wind zone settings to the shader properties on the current object - something like that. Do you have that component on the tree models? (Also, HDRP docs talked about vertex animation not being completely supported yet for ray tracing, and I think it uses vertex animation.) I think the HDRP sample scene on the asset store had a speedtree sample in it.
