 In addition to how you might normally start a JupyterLab session, it's necessary to provide two additional command line options, as follows.
 
 ```{code} bash
-jupyter lab --NotebookApp.token=<your-secret-token> --NotebookApp.allow_origin='http://localhost:3000'
+jupyter lab --IdentityProvider.token=<your-secret-token> --ServerApp.allow_origin='http://localhost:3000'
 ```
 
 The command above is fine for local development. The `token` used should align with that provided in the `project.thebe.token` key and `allow_origin` should allow connections from your myst site preview, usually running on `http://localhost:3000`.
