I'm trying to use Authorizer as an OAuth2 server (OpenID compatible).
Executing the following request:
```
/authorize?state=&client_id=&response_type=code
```
results in a redirect (even without code_challenge specified) to:
```
/app/?state=&scope=openid%20profile%20email&redirect_uri=/app&code=
```
This behaviour happens regardless of an existing session or not. In case of no session, the login form of the `/app` application is shown. However, an authorization code (`` in the path above) is already present. Is this expected without the user first proving login/consent?
I'm referring to step 4-5-6 in the below diagram (https://auth0.com/docs/get-started/authentication-and-authorization-flow/authorization-code-flow-with-proof-key-for-code-exchange-pkce#how-it-works):

Authorizer can serve as OAuth2 server while performing the "authorization code grant" flow. In this flow, a user is redirected to /authorize (https://docs.authorizer.dev/core/endpoints#authorize) which typically shows a consent screen to login and optionally configure permissions. After login, a
code
is returned which can be passed to the /oauth/token endpoint (https://docs.authorizer.dev/core/endpoints#oauthtoken).Currently, Authorizer immediately returns a
code
regardless of a consent screen.Discussed in https://github.com/authorizerdev/authorizer/discussions/334
