Facebook share for browser extensions

While trying to use Facebook JavaScript SDK I'm getting error 'Can't Load URL: The domain of this URL isn't included in the app's domains…'.

HTML

<button id="share-fb">
  Share on facebook
</button>

JavaScript

document.querySelector('#share-fb').addEventListener(
  'click',
  function () {
    shareOnFacebook(
      'https://chrome.google.com/webstore/detail/google-hangouts/nckgahadagoaajjgafhacjanaoiihapd',
      'Google Hangouts',
      'Hangouts brings conversations to life with photos, emoji, and even group video calls for free.',
      'Hangouts Team',
      'https://i.ytimg.com/vi/nZOYwpONhIQ/maxresdefault.jpg'
    )
  }
)

function shareOnFacebook(url, title, desc, caption, imageUrl) {
  window.open(
    getSharingUrl(url, title, desc, caption, imageUrl)
  )
}

function getSharingUrl(url, title, desc, caption, imageUrl) {
  let uri = `?u=${encodeURIComponent(url)}`
    + `&title=${encodeURIComponent(title)}`
    + `&description=${encodeURIComponent(desc)}`
    + `&caption=${encodeURIComponent(caption)}`
    + `&picture=${encodeURIComponent(imageUrl)}`

  return 'https://www.facebook.com/sharer/sharer.php' + uri + '&mode=group'
}
