How to use the @opentelemetry/exporter-collector.CollectorExporter function in @opentelemetry/exporter-collector

const webTracer = new WebTracer({
  plugins: [
    new DocumentLoad()
  ]
});
webTracer.addSpanProcessor(new SimpleSpanProcessor(new ConsoleSpanExporter()));

const webTracerWithZone = new WebTracer({
  scopeManager: new ZoneScopeManager(),
  plugins: [
    new DocumentLoad()
  ]
});
webTracerWithZone.addSpanProcessor(new SimpleSpanProcessor(new ConsoleSpanExporter()));
webTracerWithZone.addSpanProcessor(new SimpleSpanProcessor(new CollectorExporter()));

console.log('Current span is window', webTracerWithZone.getCurrentSpan() === window);

// example of keeping track of scope between async operations

  const element = document.getElementById('button1');
  let mainSpan = webTracerWithZone.startSpan('main-span');
  webTracerWithZone.bind(element, mainSpan);

  const onClick = () => {
    const span1 = webTracerWithZone.startSpan(`files-series-info-1`, {
      parent: webTracerWithZone.getCurrentSpan()
    });
