Hi Kenny,
Please try the following steps:
1. Log in to Webex Control Hub and select the Endpoints tab.
2. Select the endpoint you want to add a local user to.
3. Click on the Local Users tab and then click on the Add button.
4. Enter the username and password for the new user, then click Save.
5. The new user will now be added to the endpoint and can be managed from within Webex Control Hub.
Regards.
