Official source for OS version 14.0 for creating bootable drive

I am trying to create bootable drives for various versions of Mac OS. In particular, I would like to create an installer for the original version of Sonoma (14.0). However, I do not see this version listed at this site: https://support.apple.com/en-us/102662 I also don't see it available in the downloads on the developer page. Is there an official source for acquiring 14.0? PS: I found https://apple.stackexchange.com/questions/309399/how-can-i-download-an-older-version-of-os-x-macos , and this is useful and contains some older versions of Sonoma, but not 14.0. I strongly feel that at some point in history, there was a page or API you could access through the developer site that allowed downloading any OS version. I remember visiting this site 2 to 3 years ago, but I can't find it anymore.
