AWS Lambda function for forwarding SNS notifications to Slack

(event.Records || []).forEach(function (rec) {

var req = https.request(slack_req_opts, function (res) {
if (res.statusCode === 200) {
context.succeed('posted to slack');
} else {'status code: ' + res.statusCode);
req.on('error', function(e) {
console.log('problem with request: ' + e.message);;
req.write(JSON.stringify({text: JSON.stringify(rec.Sns.Message, null, ' ')})); // for testing: , channel: '@vadim'

How do I update "rec.Sns.Message" to be some custom text? Can I set "rec.Sns.Message" from somewhere in the AWS dashboard?

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?
