Hi,
I’m building a phoenix application and use Pow and Pow Assent for authentication. Pow assent requires sensitive information like provider ID and SECRET for social auth. GitHub - pow-auth/pow_assent: Multi-provider authentication for your Pow enabled app · GitHub
These values are set via environment variables.

I have added these env variables in GitHub secrets
In prod my application is unable to access these secrets. Can anybody cross check
