Is it possible to delete an imported material using script?

Collins

I have some material imported already and I can delete them in Mechanical GUI but I am curious if there is a script to delete it directly in Mechanical without using any ANsys Workbench shell or code

def DeleteObject(obj):
    try: ID = obj.ObjectId
    except: ID = obj.InternalObject.ID
    JScmds = 'DS.Tree.DeleteObject({})'.format(ID)
    ExtAPI.Application.ScriptByName("jscript").ExecuteCommand(JScmds)
