How to obtain an HttpClient for the proxied connection

[Tornhoof]

Is it possible to obtain (from code) an httpclient for the proxied connection, so I can send requests outside of the proxy to the destination.
I saw several concepts in the source, e.g. for the Active Health checks (ClusterState/ClusterModel), but I haven't found any good way to obtain the ClusterState/ClusterModel outside of the Change Listeners.
My current approach is following:

var clusterConfig = _ProxyConfigProvider.GetConfig().Clusters.FirstOrDefault(a => a.ClusterId == ProxyConstants.RouteId);
if (clusterConfig is not null && clusterConfig.Destinations is not null)
{
    var context = new ForwarderHttpClientContext
    {
        ClusterId = clusterConfig.ClusterId,
        NewMetadata = clusterConfig.Metadata,
        OldMetadata = clusterConfig.Metadata,
        OldConfig = clusterConfig.HttpClient ?? HttpClientConfig.Empty,
        NewConfig = clusterConfig.HttpClient ?? HttpClientConfig.Empty
    };
    var destination = clusterConfig.Destinations.FirstOrDefault().Value.Address;
    if (string.IsNullOrEmpty(destination))
    {
        return;
    }
    var forwarderClient = _ForwarderHttpClientFactory.CreateClient(context);
    var info = new Payload();
    var body = JsonSerializer.SerializeToUtf8Bytes(info, s_JsonSerializerOptions);
    var uri = new UriBuilder(destination) { Path = ProxyConstants.Endpoint };
    using var message = new HttpRequestMessage(HttpMethod.Post, uri.Uri);
    message.Content = new ByteArrayContent(body);
    message.Content.Headers.ContentType = new MediaTypeHeaderValue("application/json");
    using var response = await forwarderClient.SendAsync(message, cancellationToken).ConfigureAwait(false);
}

Is there an easier approach than building my own context and getting it via the factory?

Getting it from the IClusterChangeListener is the easiest option right now.
