Build a customize zoom application in React JS

I want to build a customize zoom application in React. I want to integrate it in my website and want to display heartbeat and other facial expressions of the participants in the real-time(in the live zoom meeting). I tried to explore zoom meeting web SDK for it. However I found that web SDK doesn't allow access to raw video of the zoom so I can't process it to display heartbeat and other facial expressions. 
Is this possible to get the access to the raw video for making this kind of an app?

Thank you
