+In this example, traces will be exported via OTLP/gRPC to the OpenTelemetry Collector, you can add headers or adjust the timeout settings of gRPC requests by modifying the `grpc` field. If this field is not configured, traces will be exported to the OpenTelemetry Collector using the default options via OTLP/gRPC. The example also enables the [environment resource detector](https://opentelemetry.io/docs/languages/js/resources/#adding-resources-with-environment-variables). The environment detector adds attributes from the environment variable
 `OTEL_RESOURCE_ATTRIBUTES` to the exported OpenTelemetry resource.
