For people who want a "separate window" on Chrome osX (at least), you can go on the website, click on the "..." next to your profile picture, then "Cast, save and share" > "Install website as app"

It does the same, but runs as a "separate app" so that cmd+Q only exits the app

Yes, it's pretty much the same for macOS I guess. On linux it's pretty different, I was using .desktop files over PWAs for years because of their bad UI on Linux.
