Embed dashboard - Access denied

[NT1]

Hi,

We have looker hosted at https://mycompany.cloud.looker.com/ and I a trying to use the Embed SDK to include the Dashboard in the local page - https://github.com/looker-open-source/embed-sdk . The local url is localhost:8080. 

The dashboard is getting retrieved but the data is not showing up. The URL https://mycompany.cloud.looker.com/api/internal/querymanager/queries is showing error - {"error":"Access Denied"} . What is the issue here ? Does my local url needs to be xxxx.looker.com ? 

Attached is the screenshot at well.

Thanks.
