How to use the @haul-bundler/core.InspectorClient function in @haul-bundler/core

export default async function main() {
  const {
    HAUL_INSPECTOR,
    HAUL_INSPECTOR_PORT,
    HAUL_INSPECTOR_HOST,
    NODE_INSPECTOR,
  } = process.env;
  let { haulInspector, nodeInspector } = yargsParser(process.argv);
  haulInspector = haulInspector || HAUL_INSPECTOR;
  nodeInspector = nodeInspector || NODE_INSPECTOR;

  const runtime = new Runtime(
    haulInspector || HAUL_INSPECTOR_PORT || HAUL_INSPECTOR_HOST
      ? new InspectorClient(HAUL_INSPECTOR_HOST, HAUL_INSPECTOR_PORT)
      : undefined
  );

  await runtime.ready(haulInspector === 'wait');

  // Experimental
  if (nodeInspector) {
    const wait = nodeInspector === 'wait';
    runtime.nodeInspectorStarted(wait);
    const inspector = require('inspector');
    inspector.open(undefined, undefined, wait);
  }
