Specification
https://w3c.github.io/mediacapture-screen-share/#displaymediastreamoptions


Summary

Extends DisplayMediaStreamOptions for getDisplayMedia() with a windowAudio 
option. This new option allows web applications to hint to the user agent 
whether the user should be offered the ability to share audio when a window is 
selected. windowAudio can be set to exclude, system, or window based on 
application preference. A web application that is configured for audio capture 
but wants to limit system audio capture when a window is selected should set 
windowAudio: "exclude".
