Forge Insider Will Creation Transfer Over

I know some people already have access and can download forge now on PC.
When insider comes out, part of me wants to start working on builds right away but like everything in the insiders nothing transfer over in campaign or multiplayer. So why would forge.

Is the forge beta going to be in the insider and no transfer of data or will it be in Halo infinite at launch and “beta” is just a word for things will be added and patched.
