Accessing Cognito Identity information on the server with Amplify, API Gateway, and Lambda

index.js

// In a regular Lambda function
const user = event.requestContext.authorizer.claims

// In a Serverless Express route
const user = req.apiGateway.event.requestContext.authorizer.claims

// On client
async function callApi() {
  const user = await Auth.currentAuthenticatedUser()
  const token = user.signInUserSession.idToken.jwtToken
  const requestData = {
    headers: {
      Authorization: token
    }
  }
  const data = await API.get('testrestapi', '/hello', requestData)
  console.log("data: ", data)
}

I watched your video on Youtube! it was fantastic! Would you please have a look at my issue here running this code with react native: aws-amplify/amplify-js#7670 (comment)

Hi Nader,
how to do this with cloudformation template?
Because with what you mentioned in the tutorial it will be overwritten everytime you redeploy the API with amplify.
Thank you
