How can I prevent system audio captured during screen sharing from being transmitted through the microphone audio track?

If I disable someone's microphone permissions, it will prevent the system audio from being captured properly during screen sharing.

Unfortunately, we don't support publishing a separate screen share audio track at the moment, so we mix the screenshare audio with the microphone track as a workaround.

Does the microphone have similar code? I can control the microphone input level; for example, I can set mic.gain = 0 to not capture microphone sound, and audioCapturer.gain = 0.4 to only capture system sound from the screen.
