Get microphone input data while conference call ios sdk

hello, I am developing an app that listen to the microphone input (inputNode.installTapOnBus method) and process the data by custom algorithm .
the problem is that when I open a video call via jitsi ios sdk, I no longer get data from the microphone tap.

How can I get realtime microphone raw data while video conference in jitsi ios sdk?
can I maybe give the constructor the mic buffer as dependency injection?
thanks.
