You can override fetch and do it. A sample of how to do this. You may want to filter only for your url

const { fetch: originalFetch } = globalThis;
globalThis.fetch = (...args) => {
  const [resource, config] = args;
  if (!config) {
    return originalFetch(resource as URL, { headers: { "X-CUSTOM-HEADER": "hello: } });
  }
  if (config.headers instanceof Headers) config.headers.append("origin", LOOKUP_API_ORIGIN);
  else if (Array.isArray(config.headers)) config.headers.push(["origin", LOOKUP_API_ORIGIN]);
  else config.headers = { ...(config.headers || {}), origin: LOOKUP_API_ORIGIN };
  return originalFetch(resource as URL, config);
};
