Missing Nodes in Dynamo 2.12? Can anyone help?

Good morning,
According to my research, we should have “Viewports” under Revit → Elements

I don’t seem to have these nodes. Can someone assist with how to get these?
(I don’t even know where to start)

Thank you all in advance,
Andre

Can you share screenshots of your version and library? Are you in Dynamo for Revit?
