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.

Hi, we haven’t support noise suppression yet.
Same issue is reported here.

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

Sorry but we cannot say the date for supporting it. Maybe it can be started developing this year.
