Slack Auth not working for me

[NNirosan02]

Hi, I'm following the process as described however I am unable to get authentication to work properly on the alexa developer console.

I have settings as follows:

Service Endpoint Type: AWS Lambda ARN (Amazon Resource Name) Authorization URL: https://slack.com/oauth/authorize Client Id: ***************** Access Token URI: https://slack.com/api/oauth.access Client Secret: ********************** Client Authentication Scheme: Credentials in request body

I'm not exactly sure what I should put under scope
