Using the example below, I successfully created audio profiles for different participants, but onUserUpdate did not receive any events. I’m wondering if there are any other points to note or that I need to practice.

```auto
      // Create RTMS Client
      const client = new rtms.Client();
      client.setAudioParams({
        codec: rtms.AudioCodec.L16,
        sampleRate: rtms.AudioSampleRate.SR_16K,
        channel: rtms.AudioChannel.MONO,
        dataOpt: rtms.AudioDataOption.AUDIO_MULTI_STREAMS,
        duration: 20,
        frameSize: 320,
        contentType: rtms.AudioContentType.RAW_AUDIO, 
      });
      client.onUserUpdate((op: number, participantInfo: any) => {
        logger.info(`onUserUpdate event: UUID: ${meetingUuid}, op: ${op}`);
      });
      client.onAudioData(async(){
        // (Omitted) There was successful receipt of audio data, which was actually saved as a WAV file.
      });
      client.join({
        meeting_uuid: meetingUuid,
        rtms_stream_id: streamId,
        server_urls: serverUrls,
        client: appClient,
        secret: appSecret,
        pollInterval: 10,
        timeout: 30000,
      });

```
