Someone please correct me if I’m wrong, but I’m pretty sure await has to be within an async function [0].

Yeah but we can use the same "trick" we've been using for years, an IIFE:

    (async () => { 
      // Code...
    })()

This will wait within the function, but won't block the caller.

which is what it should do

If you want the caller to "block", then it needs to await or .then() what it's calling.
