Use my approach or yours, but never use forEach with await. I don’t remember exactly why, but it just doesn’t work and will lead to very confusing errors.

Because Array.forEach doesn’t return a value or anything that could be awaited. If you use Array.map you can create an Array of promises that can be awaited with Promise.all
