  `iframeElement` element in the component's template. The `iframeElement` property is then declared
  with the `ElementRef` type, which allows access to the underlying DOM element of the iframe. This
  reference is used in the `ngAfterViewInit` lifecycle hook to attach an `onload` event handler to
  the iframe element. */
