So I have created a custom provider in next auth like this :

 {
      id: "oidc",
      name: "OIDC",
      type: "oauth",
      authorization: {
        url: "https://www.mywebsite.com/oauth2/authorize",
        params: {
          scope: "openid email profile aws.cognito.signin.user.admin",
          response_type: "code",
          client_id: process.env.CLIENT_ID,
          redirect_uri: "http://localhost:3000",
          identity_provider: "Google-OIDC",
        },
      },
      idToken: true,
      checks: ["state"],
      clientId: process.env.CLIENT_ID,
      clientSecret: process.env.CLIENT_SECRET,


    },

It works as in user can sign in with this but I am not able to create a session object as all I get from this is that user gets redirected to home page with a code in url params and now I need to send this code to exchange tokens. But how do I do it here? For some reason this provider is not even reaching the callback

callback :

session: { strategy: "jwt", maxAge: 30 * 24 * 60 * 60 },
    
      callbacks: {
        async jwt({ token, trigger, account, user, session }) {
          console.log("I am here, yes I am");

But it won't register this log while the providers as provided by next auth works fine, only my custom provider is not able to start this callback.
