Subscription Manager
Subscribing somebody does not by itself give them anything. If the product requires a PHI exception, they answer for their use of it and a reviewer decides — until then, and if it is refused, there is no access. If the service carries terms, they have to accept them. Once both are clear the subscription is provisioned into its Entra group and starts billing to a cost center.
The menu lists the areas your account can reach. If something you need is missing from it, your role does not hold that feature yet — ask a Subscription Manager administrator.
