In general, we have a rule in codebase that await should always be either the first keyword in a statement, or the first keyword on the right hand side of an assignment

I would move await to a single line above, and here just filter to avoid (async () => {})() which here makes it less readable

This can't be done since we would sequentially await in a loop.

This can be done by first assigning promise result to a variable and then filtering, but still keeping operations inside (async () => {})()
