HELP - Can the port stream based provider work in a tab application loaded by the extension?

Nobody has claimed this yet.

Can the port stream based provider work in a tab application loaded by the extension?

i.e. when a background script opens a chrome extension app in a tab - can the chrome extension app connect to MetaMask?

I am not talking about content scripts. I am talking about a chrome extension app opening in a new tab.

The reason I wanted to connect to the web browser version of metamask in the tab was so that it is associated with the extension url:

chrome-extension://oahhaapnfpkfnbgeopliehfgenifngde/tab.html#register

and not the url the content script happens to be on.

If it is not possible to connect to Meta Mask in a chrome extension tab app, then is there another way to connect the meta mask browser wallet to a domain url like:

chrome-extension://oahhaapnfpkfnbgeopliehfgenifngde/tab.html#register

I am super struggling finding the answers to this so if anyone can help me I will be super happy.

Thanks for your time.

The issue names no files, tests, or entry points. Start by reviewing the port stream provider and the documented extension connection constraints. Done means establishing whether extension tabs are supported and documenting a clear supported connection path or limitation.
