In iOS, Mute/UnMute function needs to call programatically from CallKit

I have implemented the Jitsi SDK in iOS and it is working fine. I am getting only one major issue that is, When I mute the call from Call Kit, I am not able to mute the Jitsi call, In Jitsi SDK, there is no public function which we can call.

Can you please let me know any alternate way which I can use and mute the Jitsi call from call kit screen.
