HarmonyOS 鸿蒙Next 调用notificationManager.requestEnableNotification(this.context)报错 code：1600013 message：Dialog is popping

在窗口创建并渲染后再调用

windowStage.loadContent('pages/Index', (err) => {

  if (err.code) {

    hilog.error(0x0000, 'testTag', 'Failed to load the content. Cause: %{public}s', JSON.stringify(err) ?? '');

    return;

  }

  notificationManager.requestEnableNotification().then(() => {

    hilog.info(0x0000, '’testTag', 'requestEnableNotification success');

  })

    .catch((error: BusinessError) => {

      hilog.error(0x0000, 'testTag', 'requestEnableNotification error : %{public}s', JSON.stringify(error))

    })

  hilog.info(0x0000, 'testTag', 'Succeeded in loading the content.');

});
