from a public app implementing a ui extension is there a way to do a query? None of the apis endpoints I used worked. I have been able to successfully do filters from javascript & supabase etc. but so far I can't work it out in the extension. None of the samples seem to do anything with queries.
Maybe I'm misunderstanding what is possible. I see that some other examples are using serverless functions so maybe that is what you are meant to use.
