Detect when external microphone is connected

I want my code to be notified when an external microphone is connected on mobile, is there any event that fires when a new device is connected?

I am currently doing this on Update:

 private void WatchMicrophoneDevices()
     {
         if (Microphone.devices.Length > connectedMicrophoneDevices.Length)
         {
             OnExternalMicrophoneConnected?.Invoke(Microphone.devices[Microphone.devices.Length - 1]);
         }
         else if (Microphone.devices.Length < connectedMicrophoneDevices.Length)
         {
             string diconnectedDevice = connectedMicrophoneDevices.Where(d => !Microphone.devices.Contains(d)).FirstOrDefault();
             OnExternalMicrophoneDisconnected?.Invoke(diconnectedDevice);
         }
     }
