如何让一个普通的老式外部链接与featherlight一起工作

<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/featherlight@1.7.13/release/featherlight.min.css" />
<script src="https://cdn.jsdelivr.net/npm/featherlight@1.7.13/release/featherlight.min.js"></script>

<a href="https://www.example.com" class="featherlight">点击打开外部链接</a>

<script>
    $(document).ready(function() {
        $('.featherlight').featherlight();
    });
</script>
