[Closed] How to close window

How to close window SceneExplorer by script?
3DSMAX 2016 HELP has something like:

theFrm = dotNetObject “MaxCustomControls.SceneExplorerControls.SceneExplorerDialog”
thePtr = DotNetObject “System.IntPtr” (windows.getMAXHWND())
theHwnd = (dotNetObject “System.Windows.Forms.NativeWindow”).FromHandle thePtr
theFrm.Show(theHwnd)

but this and the options don’t work
Maybe because of version 3dsmax 2022
