title: Firebase Dynamic link social info
body: <p>Faced a problem. I need to get meta information from a dynamic link. To display a preview inside my application.</p>
  <p>What I do:</p>
  <p>I am generate a link with social data:</p>
  <pre><code>const param = {
              link: config.websiteLink,
              domainUriPrefix: 'https://mysite.page.link',
              android: this._androidConfig,
              ios: this._iosConfig,
              social: {
                  title: 'SOME TITLE',
                  descriptionText: 'SOME DESCRIPTION,
                  imageUrl: 'SOME IMAGE'
              navigation: {
                  forcedRedirectEnabled: true,
              }
          }
  
  const link = await dynamicLinks().buildShortLink(param, 'SHORT');
  </code></pre>
  <p>Result:
  <strong><a href="https://mysite.page.link/TSFxds" rel="nofollow noreferrer">https://mysite.page.link/TSFxds</a> (not real link)</strong></p>
  <p>I need some logic for get this social info from 'result' link.
  I trying to use <strong>fetch(link)</strong>, but this function returns only web page without any social tags and info from link configuration.</p>
  <p>Looks like reverse engineering for firebase dynamic link =)</p>
