aah I thought about it but wasn't sure if the promise would resolve just when I want to access the url param. TypeScript does complain because it's a private property, but it works, thanks!

You for sure can build up your query in steps before using await (or .then) to "launch" it. I generate complicated queries using query = supabase.from('table') then query = query.newthing several times. If you are worried about the private property it is pretty strait forward to build up the key as you build the query by just appending filter names and values into a long string.

yeah super nice, thank you!
