How to use swagger_auto_schema in a class based view with no serializer_class and how to add custom authentication permission to it?

Question

I have a class based view as:

class ClassBasedView(GenericAPIView):
    
    @swagger_auto_schema(responses={201: 'Created'})
    @authorize(myCustomPermission)
    def post(self, *args, **kwargs) -> Response:
        // code.....
        return Response(status=HTTPStatus.CREATED)

First:

The use of swagger_auto_schema without any serializer is throwing error as: AssertionError: DetailView should either include a serializer_class attribute, or override the get_serializer_class() method.

And I don't want to use serializer for this endpoint as I don't need that. But the swagger_auto_schema keeps on throwing this error. I want to know whether there is any way to avoid the use of serializer and get the swagger documentation of this endpoint.

Second:

I want to add my custom authorisation permission of this endpoint in the doc. There is a security field in swagger_auto_schema, but don't know how to make it to use for my custom permission class ie myCustomPermission

Thanks.
