Grabbing Selection Sets with Dynamo in Revit

Hello everyone,
I am trying to grab a selection set in Revit as an alternative method because I am getting a weird error when I try to grab all of the keynote tags inside of Dynamo. I am using clockwork’s “SelectionSet.Elements” but I am unsure what to input into the node.

Cheers,

Update, it is not possible to grab keynote tags on a Revit project on the Revit Server.

why not?
