Cognito / Pinpoint integration

Hi there, I am not able to add the usage report from pinpoint to cognito. I have set up everything like in this article: https://docs.aws.amazon.com/cognito/latest/developerguide/cognito-user-pools-pinpoint-integration.html

In my client I am just using the aws-amplify sdk with following config:

authenticationFlowType: 'USER_PASSWORD_AUTH',
region: 'eu-central-1'
userPoolId: 'xxx'
userPoolWebClientId: 'yyy'

And then Auth.signIn(username, password).

Did I miss something? I thought cognito / pinpoint analytics should work out of box.

Thank you very much!
