As I'm walking through your application I"m wondering what exactly goes into the .env environment for the OAUTH sections.

It says:

    PUBLIC_CLIENT_ID                 = "129477f..."
    PUBLIC_CLIENT_REDIRECT_URI       = "c1eec90..."

    CONFIDENTIAL_CLIENT_ID           = "129477f..."
    CONFIDENTIAL_CLIENT_SECRET       = "c1eec90..."
    CONFIDENTIAL_CLIENT_REDIRECT_URI = "http://localhost:9393/callback"

    PROVIDER_URL = "http://you-server-app.com"

However whats not clear is where the PUBLIC_CLIENT_ID/PUBLIC_CLIENT_REDIRECT_URI all comes from. Is there a way I can figure this out using the doorgem-provider app how I can fill these values in?

Is it by adding an Authorized Application? If which values go where?
