Missing Create Microsoft Store Package in build settings

Hi there I’m getting to the point of packaging my game for xbox for submission. I understand I need to create a package as the Loose folder solution is for a sideload only. I thought under the build settings - Microsoft GDK - XBOX - there was an option Create Microsoft Store Package according to documentation. Mine doesn’t have that option? Any idea why? I’m using Unity 2022.3.51f1 and I do have installed the Microsoft GDK Tools and Microsoft GDK Tools for xbox.

Thank you for your help
