Stuck trying to create a runtime for a bunch of services

(property) Default: Layer.Layer<MessageClassification, never, Completions>

const openApiKey = Config.redacted('OPENAI_API_KEY');

const x = Effect.gen(function*(_) {
  const apiKey = yield* openApiKey;

  const ClientLive = OpenAiClient.layer({
    apiKey,
    transformClient: HttpClient.retryTransient({
      schedule: Schedule.spaced('1 second'),
    }),
  }).pipe(Layer.provide(FetchHttpClient.layer));

  const CompletionsLive = OpenAiCompletions.layer({ model: 'gpt-4o' }).pipe(
    Layer.provide(ClientLive),
  );

  return CompletionsLive;
});

Layer.provideMerge(MessageClassification.Default) // How to provide the layer created on X to this?
export const Runtime = ManagedRuntime.make(Logger.pretty); // How to put it here so it can run any effect that uses my service?
