  <p>I've tried using</p>
  <pre><code>headerStyle: {
        elevation: 0,
        shadowOpacity: 0,
        borderBottomWidth: 0,
      }
  </code></pre>
  <p>but according to this link
  <a href="https://reactnavigation.org/docs/native-stack-navigator#options" rel="nofollow noreferrer">https://reactnavigation.org/docs/native-stack-navigator#options</a>
  in React Navigation v6, the only property supported in headerStyle is backgroundColor only.</p>
