How to check if a member is logged in within this code?

The _memberManager.IsLoggedIn(); always return false.

I have this code works perfectly fine but I need to add a feature where it needs to check the member state.

public class TestRequestNotification : INotificationHandler<RoutingRequestNotification>
    {
        private readonly IMemberManager _memberManager;

        public TestRequestNotification(IMemberManager memberManager)
        {
            _memberManager = memberManager;

        }

        public void Handle(RoutingRequestNotification notification)
        {
            var isLoggedIn = _memberManager.IsLoggedIn(); // always return false

        }
    }
