How to get Scroll behavior > Position > Sticky with Plugin API?

No, I meant real one from Prototype tab on the right. I found way to get it with:

(await node.exportAsync({format: `JSON_REST_V1`}))
           .document
           .scrollBehavior;

But not directly from Plugin API + a way to set it.

Hmmm
Thats another question. Need to think a little. If ill have some ideas how to deal with it, ill tell ya.

I am also looking for an answer on this one.

Any update so far?
