    JupyterLab was built to support a wide variety of extensibility, including dynamic behavior based on notebook
    outputs. To access this extensibility, you should write a custom JupyterLab extension. If you would
    like trigger some behavior in response to the user executing some code in a notebook, you can output a custom
    mimetype (:ref:`rendermime`). We currently don't allow access to the JupyterLab
    API from the Javascript renderer, because this would tie the kernel and the notebook output to JupyterLab
    and make it hard for other frontends to support it.
