    This command allows a server to invite a user to join the Volume Purchase Program (VPP). It issues the invitation, but doesn't allow the server to monitor whether the user joins the program. This command yields a `NotNow` status if Setup Assistant is running.

    The command doesn't work with Account Driven enrollments.
