ChromeOS is a full Linux, it just runs Linux apps in a Debian VM. If you install anything in there it looks native, shows up in the application menu, draws it's Wayland/X11 UI just fine. Even Steam works.

You can also get ChromeOS as an ISO, but they mostly advertise it to enterprises to reuse old hardware, and not to end users. https://chromeenterprise.google/intl/en_uk/os/chromeosflex/
