[Question] [Help Needed] Issue on configuring with cognito userpool

Clarification needed section 3, step 2 in the readme file. What's the exact file destination to add those Cognito Userpool Appclient id, client id and region?

I first asked at gitter chat room [1] (4 days before) and then put a question on the group [2], unluckily no any responses received so far.
