Is there a way to get shared computer audio via Raw Data API?

Meeting SDK Type and Version
5.12.8.12615 Mac, 5.12.8.5436 iOS

Description
We are using the Raw Data API to get both audio and video from individual Zoom participants. Recently we have implemented also getting a screen sharing from a Zoom meeting.
While the video raw data for this use case works great, we have an issue with audio. We did not find a way to get the computer audio raw data from a Zoom participant if the participant selects “Share computer sound” in a screen sharing preferences. The computer audio in this case is present only in the mixed audio we get from SDK, but not in the ‘one-way’ audio we get for the specific participant.
Is there any way to get the computer audio sent by the user as a separate audio channel?
