我创建了一个简单的游戏，现在我想添加一个排行榜。我遵循了谷歌的文档，但每次当我想获得排行榜时，我都会遇到这样的错误：

W/GmsClient: IGmsServiceBroker.getService failed
java.lang.IllegalStateException: Must contain at least one of the Games scopes!

我之所以登录是因为有了这个我就知道自己的名字了

Log.d("name", String.valueOf(account.getGivenName()));

下面是getleaderboard（）的代码：

private void showLeaderboard() {
    String s = getString(R.string.leaderboard_id);
    Games.getLeaderboardsClient(this, GoogleSignIn.getLastSignedInAccount(this))
            .getLeaderboardIntent(getString(R.string.leaderboard_id))
            .addOnSuccessListener(new OnSuccessListener<Intent>() {
                @Override
                public void onSuccess(Intent intent) {
                    startActivityForResult(intent, RC_LEADERBOARD_UI);
                }
            });
}

在build.gradle中，我有：

implementation 'com.google.android.gms:play-services-auth:19.0.0'
    implementation "com.google.android.gms:play-services-games:21.0.0"

我已经创建了google控制台上的项目，我已经创建了排行榜，oauth2.0也正确设置了sha1
有什么问题？
