Deleting a space-agnostic exception container

How do you delete an exception container that is space agnostic?
"namespace_type": "agnostic"

If I try to delete it using the Exceptions API I get an error stating the list does not exist.

    {
      "message": "exception list list_id: \"my-exception-container\" does not exist",
      "status_code": 404
    }

Found the solution in the Exceptions API documentation for creating exception containers (namespace_type=agnostic).

DELETE <kibana host>:<port>/api/exception_lists?namespace_type=agnostic&list_id=<list_id>
