Cannot Disable Push Notification Sound of Android from Server Side

Expo SDK
1

I am trying to turn on and off push notification sounds from the server and it works well on iOS.

sound = 'default' if recipient['sounds'] is True else None
			push_messages.append(PushMessage(
						to=recipient['push_token'],
						body=message,
						data={'message': message},
						sound=sound))

But my Android test machine ignores ‘sound’ property and rings notification sounds every time it receives. I read that ‘sound’ property is dismissed on Android 8+, but could not find information whether it is also dismissed for Android 7 or lower versions. To sort this out, I created a channel and sent push messages with the channel id.

sound = 'default' if recipient['sounds'] is True else None
			push_messages.append(PushMessage(
						to=recipient['push_token'],
						body=message,
						data={'message': message},
						sound=sound,
						channel_id='channel_id'))

componentDidMount() {
    this.createChannelId();
}

createChannelId = async () => {
    let sounds;
    if (Platform.OS === 'android') {
      sounds = await AsyncStorage.getItem('sounds');
      if (sounds === null)
        sounds = true;
      else
        sounds = (sounds === 'true');
      Notifications.createChannelAndroidAsync('channel_id', {
        name: 'channel_id',
        sound: sounds,
      });
    }
  }

And I deleted and re-created channel every time user changes push notification sounds setting.

onSwitchSounds = value => {
		this.setState({ sounds: value }, this.onSwitchToggle);
		if (Platform.OS === 'android') {
			Notifications.deleteChannelAndroidAsync('channel_id');
			Notifications.createChannelAndroidAsync('channel_id', {
				name: 'channel_id',
				sound: value,
			});
			AsyncStorage.setItem('sounds', value.toString());
		}
	}

I finally made it, but I am not sure if it is the right way. Why does sound = None not work? Is this the only way I can manage to turn on and off notification sounds by users?
