Link filled region from Dynamo to Revit

I opened another Dynamo file on linking the filled regions to schedule

When I set up "categories " with “Filled region” node, how do I link the node to the filled region in Revit model?

filled region is a Detail item that has a type name of Filled Region
so you should select Detail item in category node then get the Type name to filler the filled region from other detail items
