I'm trying to implement an AutoFill extension for passkeys.
I need the extension to communicate with the containing app even when the containing app is terminated.
Is there any (and I mean ANY) way to do it?
P.S. I already tried the MMWormhole package and also tried to write to a file from the extension using NSFileCoordinator and observe this file in the containing app using NSFilePresenter.
Both only work when the containing app is already running.
