我已经使用了这里提供的java解决方案来解密完整性令牌https://stackoverflow.com/a/72461439/21509538，我正在解密google服务器上的令牌，而"*DecodeIntegrityTokenResponse response = play.v1().decodeIntegrityToken("com.test.android.integritysample", requestObj).execute();* "这个调用我得到了下面的错误
com.google.API.client.googleapis.json.GoogleJsonResponseException：403 Forbidden POST https://playintegrity.googleapis.com/v1/com.companyname.android.qa:decodeIntegrityToken

{
  "code": 403,
  "errors": [
    {
      "domain": "global",
      "message": "You are not authorized to decode the requested integrity token.",
      "reason": "forbidden"
    }
  ],
  "message": "You are not authorized to decode the requested integrity token.",
  "status": "PERMISSION_DENIED"
}

我必须提供什么权限，在游戏控制台上做一些改变吗？
我试图读取完整性令牌，与下面的代码的帮助
