Question Can not use noise suppression of WebRTC

We are using audio streaming of com.unity.webrtc@2.4.0-exp.5 to add chat function in our game. But there is too much background noise. It seems noise_suppression option is set to false by default in WebRTCPlugin according to the code here https://github.com/Unity-Technologies/com.unity.webrtc/blob/develop/Plugin~/WebRTCPlugin/Context.cpp .
Is it possible for us to use noise suppression in game now? Or where can we find a filter for noise reduction?
Thank you.

 

Thank you for your reply.
When shall noise suppression be supported officially? And any suggestion about noise suppression we can do now.
