Get list of all JupyterHub users?

I am running JupyterHub (version 0.8.2) on a AWS-managed kubernetes cluster (EKS).

I need to determine a way to get a list of all users. Not just the currently active users. How can I do this? It seems that the admin web UI page only shows a subset of the more recent users.

There must be some way, since JupyterHub saves the state for each user when they return

The admin page should show all users in the Hub database. You can also make an API request to /hub/api/users as an admin to get a complete list.

What Authenticator are you using?
