How to set matrix to slice node?

matrix_transform = np.array([
[1, 0, 0, 0.2],
[0, 1, 0, 0.3],
[0, 0, 1, 0.4],
[0, 0, 0, 1]
])

viewNode = ‘Green’
sliceNode = slicer.app.layoutManager().sliceWidget(viewNode).mrmlSliceNode()
sliceNode.SetSliceTORAS(slicer.util.vtkMatrixFromArray(matrix_transform))
sliceNode.UpdateMatrices()
AttributeError: ‘MRMLCore.vtkMRMLSliceNode’ object has no attribute ‘SetSliceTORAS’
