+- `oauth_no_confirm: bool (default - False)` - When set to true,

+  By default, when users authenticate with a service using JupyterHub,

+  Skipping the confirmation page is useful for admin-managed services that are considered part of the Hub

 If a service is also to be managed by the Hub, it has a few extra options:
 
 - `command: (str/Popen list)` - Command for JupyterHub to spawn the service. - Only use this if the service should be a subprocess. - If command is not specified, the Service is assumed to be managed
