activate Fauxton UI in pouchdb-aws-serverless

I need someone to show me how to activate the Fauxton UI (User Interface in https://github.com/pouchdb/pouchdb-fauxton) in pouchdb-aws-serverless (https://github.com/KouchDB/pouchdb-aws-serverless). I am not sure if it has to be installed separately or is already included. Currently when I try to hit the "/_utils" endpoint in an installed instance of pouchdb-aws-serverless, I get an error. Instead of error I should get the Fauxton UI in my web browser.
