Niagara leaves and parameter collection

Hi guys! I am weak in functions, so I will be glad to help.
I have a material parameter collection, I connect it to the materials of objects that sway in the wind. Everything works, but I don’t know how to connect it to the fall leaves, which is made with Niagara. I think that you need to create a BP in which you need to combine niagara and parameter collection. But I don’t understand how to do it.
