Ah, i think that one was changed. Seems like that the documentation is not up to date for it. You would need to modify the united-manufacturing-hub-hivemqce-extension configmap to create your users and roles and then restart the hivemq pod. https://github.com/united-manufacturing-hub/united-manufacturing-hub/blob/staging/deployment/united-manufacturing-hub/templates/hivemq/config-extensions.yaml
