小白请教问题，使用uni pay中的下面函数，退款，结果报错说没有权限。查了以下文档，应该是要uni-id中需要设置权限。但是，并没有设置权限的教程。网上查找也没有解决方法。希望大神出一个手把手教学的教程。
let res = await this.$refs.pay.refund({
out_trade_no: this.orderMangeItem.outTradeNo, // 插件支付单号
});

感谢回答！我看uni pay的部分代码找到解决方案了。设置了用户权限，但是还需要获取新的tocken，才可以获得最新的用户权限。但是，又遇到其他问题。

证书都配置好了，用的是 v2。目前没有找到解决方案

回复 3***@qq.com: 改成v3,目前node18不支持v2版本的微信支付的退款API了,因为p12证书的格式被node18废弃了
