access github resources through dex

[zsaladin]

I'm integrating dex with github and my client app.

Based on my knowledge dex is used as a proxy for supporting oidc between client and oauth2.0 idp like github. In this case dex stores access token issued from github and issues own access token and id token to client. The client doesn't know github. Dex is the only one the client connect to.

My question is that how the client access github resources? The access token the client has is JWT and issued from dex. So github has no idea about this access token.

Give me some advice and feel free to correct me if I was wrong.
