Task Scheduler and CAM

I had a question regarding configuration settings for the new Task Scheduler in UX. According to the Screensteps article, we need to store credentials in the “taskSettings” parameter in settings.json.

If we are using CAM authentication (SecurityMode=5) without SSO, where can we specify the CAM Namespace? Do we need to append it to the front of username (e.g., AD\username) or is there a separate parameter to use? Thanks!
