title: How do I know the data is empty on Trustpilot Embeded?
body: <p>I'm following this <a href="https://support.trustpilot.com/hc/en-us/articles/203840826-Add-a-TrustBox-to-a-webpage" rel="nofollow noreferrer">instruction</a> to embed the Trustpilot on my website. It will render a  tag that contains the data.
  I would like to check when the data is empty like this:</p>
  <p><a href="https://i.stack.imgur.com/xpg9V.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/xpg9V.png" alt="enter image description here" /></a></p>
  <p>I found that the Trustpilot will create an object like this window.Trustpilot.Modules.WidgetManagement but still don't know how to detect that the data is empty or not.</p>
