Get Form combobox macro name with code

Was wondering if there is a similar way (as below) or a different way to grab the "Macro name:" value of the macro assigned to an old Form combobox.  Thank you very much.

Had similar question with ID 26805164  where I was looking to grab the "Input range:" and "Cell link:" values of an old Form combobox.  That question was answered with the following code:

Sub GetProps()
    Dim S As Shape
    For Each S In ActiveSheet.Shapes
        If S.Type = msoFormControl Then
            If S.FormControlType = xlDropDown Then
                S.Select
                MsgBox Selection.Name & vbCrLf & Selection.ListFillRange & vbCrLf & Selection.LinkedCell
            End If
        End If
    Next
End Sub
