You can add or remove Live Assist administrators by using the admin portal. (Learn how to access the admin portal.)
Important: Do not add or remove the Live Assist Administrator role from a user by using the Manage User Roles setting in Dynamics 365. That can cause problems. Instead, please make the change using the admin portal as explained in this article.
In the admin portal, go to the Users menu and then click on Admins.
Clicking on the Make Admin button next to the name of the user will assign the administrator role to that user.
You can also search based on first name and last name by typing into the search box and then pressing enter or clicking on the search button.
