UIExtension get widget reference after registering it

It’s been a while since I wrote my answer, but if I recall you can pass any UObject into the node Register Extension’s Data pin (see image 1), and on the other end, in either the Get Widget Class for Data or Configure Widget for Data bindings which you can create (see image 2), you will have to cast to your type to recover the original data intact. Does that help you in any way?
