如何实现Ant design 菜单的滚动条效果?

如上图所示,是一个Ant design下拉菜单的样式:有一个列表,包含若干条数据,当不滚动的时候滚动条隐藏,当滚动鼠标的时候滚动条显示,停止滚动后消失。

当前我自己的滚动列表是这个亚子,滚动条丑丑的

demo代码如下,使用::-webkit-scrollbar ::-webkit-scrollbar-track
::-webkit-scrollbar-thumb设置滚动条样式好像没效果,还是我写得有问题?

综上,请问这个需求该怎么实现呢?只实现样式的改变也行!!!
o(╥﹏╥)o

index.ts

import { Card, List} from "antd";
import styles from './styles.less';

const demo:React.FC=()=>{

    const data = [
        '1',
        '1',
        '1',
        '1',
        '1',
        '1',
        '1',
        '1',
        '1',
        '1',
        '1',
        '1',
        '1',
        '1',
        '1',
        '1',
        '1',
        '1',
        '1',
        '1',
      ];

    return (
        <div>
                <Card title='选择列表' className={styles.card} bordered={false}>
                        <List
                            size="small"
                            bordered
                            dataSource={data}
                            renderItem={(item:any) => <List.Item>{item}</List.Item>}
                            className={styles.List}
                        />
                </Card>
