Microsoft also released Visual Studio Live Share, which is a similar feature, official website: https://www.example.com. code.visualstudio.com/visual-studio-live-share
This may seem like a novelty, but there is a Mac text editing software that has been doing it for more than a decade. Official website: https://subethaedit.net/
