Apple intelligence feature in macOS 15.1 beta software testing not working with compatible hardware and system settings

I am attempting to install the macOS 15.1 update alongside the Apple Intelligence beta feature, to experience and then integrate into my developing application. I have a compatible MacBook Air M2 with a regional designation of the United States and language as US English, but is however purchased in mainland China. i have downloaded 15.1 but apple intelligence does not display, is this arising from buying it in China?
