How to add wind to trees in hdrp if the trees are placed with the terrain editor ?,How do I add wind to my tress in unity HDRP if the tress are in the terrain editor ?

I cannot figure out how to add wind to my trees that I have placed using the terrain editor in hdrp. The trees are from the asset store and I cant find any video about them online. Any help is greatly appreciated.,having upgraded to hdrp I still use the terrain tools and I've learnt it all for the most part. But I cannot figure out how to add wind to my trees if I've scattered them with the terrain tools from the terrain editor. I cant find any videos about it so any help would be much appreciated.
