Why not just use ask cli? Don't answer this I might just start screaming and never stop
Consider, you can have a lambda function provision a new account from AWS Control Tower, and expose that as a WebSocket-based AWS Chalice API connected to ChatOps in Slack. That's pretty cool.
“ask cli”? Do you mean AWS CLI? Or SAM CLI?
https://aws.github.io/chalice/ is a bit better as an entry point, though that could also be a bit clearer on what problems Chalice solves
