   1. Create a Microsoft Entra test user - to test Microsoft Entra single sign-on with B.Simon.
   2. Assign the Microsoft Entra test user - to enable B.Simon to use Microsoft Entra single sign-on.
2. Configure Sketch SSO - to configure the single sign-on settings on application side.
3. Test SSO - to verify whether the configuration works.
