Signing out with MSAL removes all known information about a user from the application, but the user will still have an active session on their device. If the user attempts to sign in again they may see sign-in UI, but may not need to reenter their credentials because the device session is still active.
Как я могу завершить сеанс после выхода из системы с помощью MSGraph?
