Play MakeCode Arcade Game In App

With reference to this, just recently about some developments on Kiosk Mode, but now back a bit more on topic here:

Just checked out https://arcade.makecode.com/kiosk, and it looks good, and seemingly multiplayer capable as well.

But how would one go about making for instance a school arcade project with student’s games on some minimum capable and low powered hardware/pad, with for instance the shoebox controller, but not with the official shared makecode.com site and preloaded games or others’ uploaded games in the mix(and maybe no stable internet)?

The idea is that you put the RPI in kiosk mode and have it load this webpage fullscreen. This page accepts gamepad input, so you can build a cabinet using gamepads or an arcade button kit with gamepad support. You can add new games using a phone and the button in the top right.

Is the idea only to run this official site, or also to run a local kiosk server on the device or another connected device. Is it(will it be) also a self-contained (boot)image or app that one can download? How to isolate it from the default game/other users(log in/user profiles/session cookies?)? How to configure it; the menus, artwork, school logo etc.? Does it have to be a mega Chrome-based browser, or would lighter/minimal browsers work?

I understand it is cool with many new opportunities, and enabling the use of new devices and OS’es, but then, as I almost imagined a use case “as/like an app” or a project, it eluded me… Sorry for being slow here.

Anyone have examples of it in use that they would like to share for inspiration?
