How to create a new (public) game instance/server without creating a new place?

As I do not know how to even begin to do such, I have no code to provide. Although I do plan to run it from a localscript.

There is already a similar question that got an answer: https://scriptinghelpers.org/questions/22800/create-new-server-and-send-player-to-it

But it doesn't mention how to even create a reserved server with scripts, it just says you can and the wiki provides no information on such: https://developer.roblox.com/api-reference/function/TeleportService/ReserveServer

I don't want to really have a private server created anyways, I want a public form that anyone can join.

And besides, I don't think 'creating a new place' equals 'making a new game server' since I'd assume you couldn't join a game instance via the game's game instances.

I'd think there 'ought to be a feature to create a new server, otherwise could someone of high ranking recommend it to upper Roblox staff/developers? It'd be an outstanding feature!
