我需要在所有 WordPress 管理页面（后端）上添加 Livechat 小部件。

Livechat JavaScript 代码是这样的：

<!-- Start of LiveChat (www.livechatinc.com) code -->
<script type="text/javascript">
window.__lc = window.__lc || {};
window.__lc.license = 12345678;
(function() {
  var lc = document.createElement('script'); lc.type = 'text/javascript'; lc.async = true;
  lc.src = ('https:' == document.location.protocol ? 'https://' : 'http://') + 'cdn.livechatinc.com/tracking.js';
  var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(lc, s);
})();
</script>

powered by <a href="https://www.livechatinc.com/?welcome" rel="noopener nofollow" target="_blank">LiveChat</a>
</noscript>
<!-- End of LiveChat code -->

Livechat 有一个可以在前端页面上进行聊天的插件。我实际上想将此代码添加到 WordPress 后端的每个页面。 …
