Generally speaking, you are not allowed by your terms of use agreement to discuss in public any a beta OS.

With that said, creating a bootable installer has been unchanged for quite some time.:

Also keep in mind this "Sonoma" Mac must also be compatible with the OS you want to create a USB installer....which in this case does your Sonoma Mac support Catalina? If not, then you will need to find another Mac generally from 2012 to 2019 to use to download & create the bootable macOS 10.15 USB installer.
