    ⚠️ 注意事项：
    <ul style="margin-left: 30px">
        <li>设置自定义表情后需输入 : 或点击工具栏上的表情按钮才可查看到效果</li>
        <li>设置表情提示文案后需点击工具栏上的表情按钮才可查看到效果</li>
        <li>设置表情图片地址后需在调试栏中查看表情图片地址才可看到效果，试一试 :wulina: 表情图片吧</li>
        <li>At、话题等扩展功能的回调中 value 值需以 `key` 开头</li>
        <li>当启用 At、话题等扩展功能时，可使用 options.hint.delay 来减少服务器压力</li>
