Minecraft Launcher for Xbox Developer Mode

Hello Mojang, I would like to ask you to create a version of the Minecraft Launcher compatible with Xbox Developer Mode. It would have controller support and the ability to download and launch games. Along with that, please add mouse and keyboard support on Xbox to Minecraft: Java Edition and the launcher (if it already does don't worry about it).

I would love this because my computer isn't all that great and my Xbox can run a lot of high-demand games.

If you have time, maybe you could add your Minecraft: Dev to the Xbox Minecraft Launcher as well (because it's called Xbox Developer Mode).
You know which Minecraft version I'm talking about. The one that's not public? Yea, THAT Minecraft: Dev.

Anyway, thanks for reading and I hope you do add this.

QUESTION: Why can't you add Minecraft: Java Edition to Xbox anyway?
