Unfortunately, it's not that simple. A PWA can still be opened in a tab in a normal browser window (at least I'm not aware of controls to prevent this), and browser kiosk mode still allows other tabs to be open (and at least with hot corners and virtual desktops in MacOS or Linux, you can navigate to other app windows). I was referring to Electron's kiosk mode, which can be restricted a little more IIRC (but it's still not enough to prevent all attempts to navigate away from it, or at least wasn't when I worked on such an app in v6 or v7 IIRC).
I think you can use a PWA for this, which will launch the browser without the url or tab available :)
(Or as Mike said, use a browser in kiosk mode)

Looks like I’ll have to look more into using electron. In the meantime maybe a PWA and kiosk mode could sold some use cases.
