How to use the react-native-code-push.disallowRestart function in react-native-code-push

const syncImmediate = () => {
  console.info('[CodePush]syncImmediate: 安装更新并立刻重启应用')
  CodePush.disallowRestart() // 禁止重启
  CodePush.sync({ installMode: CodePush.InstallMode.IMMEDIATE }, codePushStatusDidChange, progress => {
    console.info('[CodePush]codePushDownloadDidProgress: ', progress)
    if (progress.receivedBytes >= progress.totalBytes) {
      console.info('[CodePush]syncImmediate-强制更新')
      CodePush.allowRestart() // 强制更新
    }
  })
}

static deal(update) {
        NavigationUtil.showLoadingOverLayOrModal("0%");
        codePush.disallowRestart();
        //确定之后，开始下载
        update.download(CheckCodePushUpdateUtil.down).then(instance => {
            //下载完成了，调用这个方法
            console.log("开始安装");
            instance.install(codePush.InstallMode.IMMEDIATE).then(() => {
                console.log("安装完成");
                codePush.notifyAppReady();
                codePush.allowRestart();
                codePush.restartApp(true);
            }).catch(reason => {
                CheckCodePushUpdateUtil.error();
            });
        }).catch((reason) => {
