Hello ,Welcome to MS Q&A
The User role in Microsoft Graph API is generally used to manage user-related functionalities within an application or service. It allows users to perform actions such as reading user profiles, managing user accounts, and assigning roles. Whether this role can be assigned to any user depends on the permissions and scope defined in the application. Typically, roles can be assigned based on the user's membership in a group or directly to the user, but specific permissions may be required to assign certain roles.
