Since [Highlight](https://www.highlight.io) natively supports OpenTelemetry, you just need to route the traces to Highlights's OTLP endpoint and set the
highlight project id in the headers:

```bash theme={null}
TRACELOOP_BASE_URL=https://otel.highlight.io:4318
TRACELOOP_HEADERS="x-highlight-project=<YOUR_HIGHLIGHT_PROJECT_ID>"
```
