• The JSX syntax is incorrect. The function should return the JSX element, not use a semicolon after it. Should be return <div>...</div>; or remove the semicolon and add proper return statement.

  const { track } = useTrack();
  <div>
    <button onClick={() => track("Huddle Started", { huddleType: "voice" })}>
      Start voice huddle!
    </button>
  </div>;
