Hi! I am not being able to access the function [setHiddenNodeIDs](https://apidocs.slicer.org/master/classqMRMLSortFilterProxyModel.html#a65d2c0a4108b992de0fdd9d7e511e2a7) from inside my Slicer. Using 4.11.0-2020-01-20 r28737.

hiddenNodeIDs is a property, so you can write it as `something.hiddenNodeIDs=["vtkMRMLMarkupsCurveNode", "vtkMRMLMarkupsLineNode"]`
