Since it is in the beta version, you may use your developer account, if you don’t have it, use the Install Assistant.pkg.
What is InstallAssistant.pkg?
Install Assistant is not a very big deal since its only purpose is to contain the macOS’s data in a cage inside itself. And when you install the Install assistant.pkg it will combine them and extract them on the Applications directory.
The good thing about the Install Assistant is that it is provided by Apple for the developers. You can also get it from the Apple servers as long as you have a developer account.
