	privateKeyBytes, err := os.ReadFile(os.ExpandEnv("/path/to/your/private/key/file.key"))
	if err != nil {
		log.Fatalf("Error creating logger: %s", err)
	}

	client, err := sfdcclient.NewClientWithJWTBearer(

		},
	)
	if err != nil {
		log.Fatalf("Error initializing connected app salesforce client: %s", err)
	}

	url := "/services/data/v47.0/sobjects/MySObjectName/describe" // note that this is a relative URL to the salesforce instance server URL
	statusCode, resBody, err := client.SendRequest(context.Background(), http.MethodGet, url, nil, nil)
	if err != nil {
		log.Fatalf("Error sending salesforce request: %s", err)
	}

	fmt.Printf("\nResponse status code: %d", statusCode) // -1 if an error is returned by the SendRequest call
