Hello,

What wanting to do)  
When a user is speaking but his or her microphone is muted, I want to display a message saying “Are you talking? Press the microphone to turn it on.”

For Twilio)  
When using `Twilio`, I could sample the microphone input like this:

```kotlin
    private val audioSink = AudioSink { audioSample, _, _, _ ->
        val microphoneLevel = audioSample.get().toInt().absoluteValue
        if (microphoneLevel > 50) showMessage("Are you talking? Press the microphone to turn it on.")
    }
    
    localAudioTrack?.addSink(audioSink)

```

What I tried)  
I’ve checked the following events, but after local user being muted there is no event raised.

```kotlin
override fun onUserAudioStatusChanged(audioHelper: ZoomVideoSDKAudioHelper?, userList: MutableList<ZoomVideoSDKUser>) {
    val localUser = userList.firstOrNull { it.userID == zoomSession?.mySelf?.userID } ?: return
    Log.d(TAG, "onUserAudioStatusChanged(isTalking: ${localUser.audioStatus.isTalking})")
}

override fun onUserActiveAudioChanged(audioHelper: ZoomVideoSDKAudioHelper?, userList: MutableList<ZoomVideoSDKUser>) {
    val localUser = userList.firstOrNull { it.userID == zoomSession?.mySelf?.userID } ?: return
    Log.d(TAG, "onUserActiveAudioChanged(isTalking: ${localUser.audioStatus.isTalking})")
}

```

Inquiry)  
Would there be a way to do the same as `Twilio`?

Environment)  
Platform: Android  
Zoom SDK: us.zoom.videosdk:zoomvideosdk-core=1.12.5  
Test Device: Pixel 3a (Android ver. 12.0)

Thanks
