    This loader is not compatible with all Blackboard courses. It is only
    compatible with courses that use the new Blackboard interface.
    To use this loader, you must have the BbRouter cookie. You can get this
    cookie by logging into the course and then copying the value of the
    BbRouter cookie from the browser's developer tools.
    Example:
        .. code-block:: python
            from langchain.document_loaders import BlackboardLoader
            loader = BlackboardLoader(
                blackboard_course_url="https://blackboard.example.com/webapps/blackboard/execute/announcement?method=search&context=course_entry&course_id=_123456_1",
