Docs clarification - using EAS Build for iOS associatedDomains

The docs for the associatedDomains configuration for universal linking states the following for the Bare Workflow:

Build with EAS, or use Xcode to enable this capability manually.

I’m curious about the “Build with EAS” part. AFAIK, app.json isn’t used in the bare workflow… or is there some buildtime compilation that pulls select keys from this config into the platform-specific build configuration?

I’m working on a PR to clarify the docs relating to universal linking, but I can’t find what “Build with EAS” means in this context.
