title: tel:{phone_number} link [Action.OpenUrl] not working on web in adaptive card microsoft teams from Chat
body: <p>We have added a button of type <strong>Action.OpenUrl</strong> in adaptive card and its url as a <strong>tel link</strong> as given below.</p>
  <pre><code>&quot;actions&quot;:[
    {
       &quot;type&quot;:&quot;Action.OpenUrl&quot;,
       &quot;title&quot;:&quot;Call Mobile&quot;,
       &quot;url&quot;:&quot;tel:+919090909095&quot;
    }
  ]
  </code></pre>
  <p>It was apparently working fine few days back but have stopped working suddenly.
  If we add any valid url as any like this,</p>
  <pre><code>&quot;actions&quot;:[
    {
       &quot;type&quot;:&quot;Action.OpenUrl&quot;,
       &quot;title&quot;:&quot;Call Mobile&quot;,
       &quot;url&quot;:&quot;https://www.google.com/&quot;
    }
  ]
  </code></pre>
  <p>It works fine but our requirement is to open our phone app hence the tel link.
  We already raised the same issue from <a href="https://stackoverflow.com/questions/72261665/telphonenumber-link-in-adaptive-card-not-working-in-channel-in-microsoft-team">channel section</a>, but from chat it was working fine earlier.</p>
