block editor - Interactivity API using withScope

I'm attempting to use the interactivity API for the first time. It seems to require using withScope in order to get some context from form filters. I can test individual pieces of my code and they work, but anything within withScope does not seem to run at all, even if I dumb down the code as much as possible There are no console errors, the file loads and the other pieces of it run. I read something that was over my head about withScope potentially not working in an async context.
