        This page uses the <strong>unstable_getServerSession()</strong> method

        Using <strong>unstable_getServerSession()</strong> in{" "}
        <strong>getServerSideProps()</strong> is the recommended approach if you
        need to support Server Side Rendering with authentication.

      <p>
        The advantage of Server Side Rendering is this page does not require
        client side JavaScript.

      <p>
        The disadvantage of Server Side Rendering is that this page is slower to
        render.
