How to get Blueprint "ParentClass" property from Python?

Hi, I am trying to get Blueprint object ParentClass property for a custom plugin but it is protected, is there any other way I could access it?

ue.log(ue.load_asset(name="Blueprint'/Game/NewBlueprint1.NewBlueprint1'").get_editor_property("ParentClass"))

LogPython: Error: Exception: Blueprint: Property 'ParentClass' for attribute 'ParentClass' on 'Blueprint' is protected and cannot be read
