Isolated Pick Model Elements

Hi everyone, I just opened Revit and Dynamo under manage tab.

Question1 I am trying to add “Isolated Pick Model Elements” node but I cannot find it under Search tab or Revit>Selection.

Also when i open “Select Model Elements” and click “Select”
The Revit model is missing “Multiple, Finish, Cancel” button

How do I successfully connect Dynamo to Rhino model?

for isolate model element, you could find the node in packages like archi-lab

for selecting model element, there are two nodes , one for instance selection - one element which has a name " select model element", and the other node for multiple element selection that has a name " select model elements"
once you select it will be finished automatically, and for cancellation just click in any empty area
