Testing the feature manually guide

Step 1: Test unauthenticated access

1. Visit the Contact Page without logging in.
2. Check for Visibility: Verify that the Altinn service desk information is not visible. This ensures that unauthenticated users do not have access to "sensitive" or not preferred information to show service desk information.

Step 2: Test access for authorized user

1. Login with an Account that has access to an organization.
2. Verify the Altinn Service Desk Information: Ensure that after logging in, the Altinn service desk information becomes visible. This confirms that authorized users can view the relevant service desk information.

Step 3: Test access for unauthorized users

1. Login with a User who does not belong to the organization or does not have the necessary access rights.
2. Check for the Hidden Altinn Service Desk Information: Confirm that the Altinn service desk information is hidden for users without proper permissions. This test ensures that unauthorized users cannot see the service desk information.
