I deleted some default users and now can't use my Open EDS instance properly

I accidentally deleted some default users in my openEdz instance. Can’t remember their names.
Since then I am in trouble running my instance.

First, when I try to log in the studio I get the error: “OAuth Client for the Login service, ‘login-service-client-id’, is not configured”, but if I reload the page I’m logged in.

I think that what caused the problem was the deletion of the user “login_service_user”.

The users I deleted was: login_service_user, ecommerce_worker and cms

How can I recreate these users?

This migration creates the login service worker and this one creates the ecommerce worker.

There’s also an ansible task in edx/configuration that generates a bunch of service workers that might give you a clue on how to restore them.
