HTTP Integrations using GoLang for the chirpstack-simulator

I am trying to use the ChirpStack-Simulator and it works great! The issue that I am having now is that I need it to generate HTTP Integrations when it creates the devices, however I am not sure of how to do that using GoLang and the libraries that were created. I have the following and if anyone can point me in the right direction I would appreciate it.

Code Sample:

    func (s *simulation) setupHttpIntegrations() error {
        log.Info("simulator: create integrations")

        createIntResp, err := as.Integration().Create(context.Background(), &api.CreateHTTPIntegrationRequest{
	      Integration: &api.Integrations{
		  AckNotificationUrl: "https://localhost:8080/api/data/ack",
		  ErrorNotificationUrl: "https://localhost:8080/api/data/error",
		  JoinNotificationUrl: "https://localhost:8080/api/data/join",
		  LocationNotificationUrl: "https://localhost:8080/api/data/location",
		  StatusNotificationUrl: "https://localhost:8080/api/data/status",
		  TxAckNotificationUrl: "https://localhost:8080/api/data/txack",
		  UplinkDataUrl: "https://localhost:8080/api/data/uplink",
  if err != nil {
	  return errors.Wrap(err, "create integrations error")
  return nil }
