Newbie here - Can someone explain in little more detail on how to add this into a Lambda? I created a Lambda function, chose its runtime to be Nodejs 10.x and it opens with a default file of index.js. I assume I can not copy and paste this code into the index.js? Anything else special needed to call this from SNS?
