Just to add to pointer....
https://github.com/aws-samples/step-functions-workflows-collection/tree/main/parallel-human-approval
above github flow is different from mine reason:

1. My flow will present user with SNS mail that display a one click workflow reject or approval link
   it envolves --> lambda--> SNS (API GW link of approval or denial ) --> requester click on approve or deny
2. The existing one send the token in the mail and thats not useful until some make the api call to SFN to approve it.
3. I have worked on Ent cx and already shared this solun which they liked.
