GET WebView's WebNavigatedEventArgs Result Error Code when successful in .NET MAUI

It seems that when Navigated event occurs, the Result from the navigation of the WebView in .NET MAUI is successful, no matter that the response status is 401 for example. (Unauthorized).

I was counting that it will be Failure, for anything but 2xx. Is there a way to detect problem when loading the WebView?

(Perhaps without writing too much platform specific code)

Edit(adding some related code):

void Navigated(WebNavigatedEventArgs args)
{            
    if (args.Result == WebNavigationResult.Failure)
    {
        IsConnectionOK = false;
    }
}

The Result here is success, not failure. The HTTP response status of the request is 401. (Unauthorized)
