Type hint for dictionary view objects

I'm not sure the documentation contains any concrete info on the type of view objects. I wasn't able to locate it (i.e. <class 'dict_values'> in the dict's source code. Is there a way to explicitly specify this 'view class'? And does it make sense in the first place? Example:

def func1(arg: dictview) -> None:
    pass

collections.abc.MappingView
collections.abc.ItemsView
