Jupyterhub to Github authentication using secrets

Hi Team,

I did a setup of Jupyrthub authentication with Github via hub.config. This was working perfect but due to secret protection we need to fetch client secret from ext secret manager here AWS secret manager. So I did created a k8s secret using external secret for the same but how can I pass it in config so that Jupyterhub gets it ? Any help is highly appreciated.

    jupyterhub:
      hub:
        config:
          GitHubOAuthenticator:
            client_id: xxx
            client_secret: yyy
            oauth_callback_url: https://<my-domain>hub/oauth_callback
