const unsanitizedHtmlPolicy = trustedTypes.createPolicy('unsanitizedHtml', {
  createHTML: (htmlString) => htmlString,
});

document.head
  .querySelector(':first-child')
  .insertAdjacentHTML(
    'beforebegin',
    unsanitizedHtmlPolicy.createHTML(
      `<link rel="manifest" href='data:application/manifest+json,{"start_url":"${startUrl}"}' />`,
