 The most relevant fields here are `code`, which contains the code itself, and `accept_url`, which is the URL path for the page another user.
 Note: it does not contain the _hostname_ of the hub, which JupyterHub often does not know.
+If `public_url` configuration is defined, `full_accept_url` will be the full URL including the host.
+Otherwise, it will be null.
