我正在使用Firebase Cloud Messaging，使用react-native-push-notification将通知从mongoDB发送到react-native应用程序。
通知工作正常，但我无法播放我在/res/raw文件夹中添加的自定义通知。

我的代码：

const message = {
    "to": userFinded.deviceToken,
    "notification": {
      "title": 'Body test',
      "color": '#ff9d00',
      "sound": 'my_sound', //Not working
    },
  };

FCM文档
我也尝试遵循documentation of react-native-push-notification并执行以下操作：

PushNotification.localNotification({
    /* Android Only Properties */
    channelId: 'fcm_fallback_notification_channel', // (required) channelId, if the channel doesn't exist, notification will not trigger.

    soundName: 'my_sound.mp3', // (optional) Sound to play when the notification is shown. Value of 'default' plays the default sound. It can be set to a custom sound such as 'android.resource://com.xyz/raw/my_sound'. It will look for the 'my_sound' audio file in 'res/raw' directory and play it. default: 'default' (default sound is played)
  });

  PushNotification.createChannel(
    {
      channelId: 'fcm_fallback_notification_channel', // (required)
      channelName: 'My channel', // (required)
      soundName: 'my_sound.mp3', // (optional) See `soundName` parameter of `localNotification` function
    });

我尝试了不同的版本：

soundName: 'my_sound.mp3';
soundName: 'my_sound';
soundName: 'android.resource://com.xyz/raw/my_sound';
soundName: 'android.resource://com.seeed/raw/my_sound';

有时通知声音是默认的，有时我没有任何声音。
有什么需要帮忙的吗？
