我是auth 0的新手，也是为手机构建应用程序的新手。
我已经将auth 0集成到我的项目中，这是一个react本地应用程序。
因此，我目前在这里使用一个本地项目。
我也创建了一个M2M来帮助我连接到一个API来对用户进行更改，但是我得到了一个错误
“access_denied：{“error”：“access_denied”，“error_description”：“客户端未被授权访问“https：//[URL-ACCESS]/API/v2/".您需要创建一个与此API关联的“client-grant”。请参阅：Auth 0管理API v2
我不确定我是否错过了任何设置或任何其他步骤。请注意，我确实授权了M2M，并授予了它所有的范围。
这是我使用的代码，我从我的服务器Node.js发出调用，我的前端正在传递值React Native。

const express = require('express');
const { ManagementClient } = require('auth0');
const url = require('url');
const { authenticate } = require('./middlewares');

router.get('/authenticated', (req, res) => {
  res.send('You are authenticated!');
});

  // You can add additional checks here to confirm the user has the 'admin' role.
  res.send('You are an admin!');
});

  if (picture && !url.parse(picture).hostname) {

  }

    console.error(error);

module.exports = router;

我需要能够更新正在从我的前端React Native发送的用户信息
