How to communicate with external pages ?

My scenario is to use the IDE nested in a page, and I need to control the file content in the IDE through the page. Is there any way to expose the memfs instance? thanks !

My version of this has a very minimal patch to allow extensions to postMessage up to the host page, which allows you to transfer a MessageChannel port from an extension, allowing further communication.
