Just to check if you are placing this config in right file, this must go into `jupyter_server_config.py` that is placed in one of the config directories reported by `jupyter --paths` in your JupyterLab server.

Once the config is placed in right file, assuming your JupyterHub user is `foo` and you are using a unnamed default server, you must verify the new registered endpoint at `https://myFQDN/hub/foo/test-server/`.
