It also requires evidence of substantial progress on the feature. It sounds like here, the original experiment did not go as planned due to a dependency. Do you know if the isolated web apps feature is ready now? In other words, is this dependency satisfied? > Contact emails > > simo...@google.com > > Explainer > > https://github.com/screen-share/capture-all-screens/blob/main/README.md > > Specification > > https://screen-share.github.io/capture-all-screens > > Design docs > > https://screen-share.github.io/capture-all-screens > > https://github.com/screen-share/capture-all-screens/blob/main/README.md > > > https://docs.google.com/document/d/13el0NriAUpAzLUw96V7zQiMSjgH9zVaTXUHtuaq8-HI/edit?resourcekey=0-jRPpeLth1odq6M5iFLswig > > Summary > > Capture all the screens currently connected to the device using > getAllScreensMedia().
