Description

Describe the bug
When trying to authenticate with an OIDC provider that utilizes https://datatracker.ietf.org/doc/html/rfc7523 (JSON Web Token (JWT) Profile for OAuth 2.0 Client Authentication and Authorization Grants) - it is not possible to use the convenience function authStateByPresentingAuthorizationRequest

This function calls the OIDAuthorizationResponse tokenExchangeRequest - rather than allowing to pass through Additional Parameters by allowing the use of OIDAuthorizationResponse tokenExchangeRequestWithAdditionalParameters - even where Additional Parameters are passed to OIDAuthState

This seems like a workflow that has been overlooked.

Research direction

Trace authStateByPresentingAuthorizationRequest into OIDAuthorizationResponse tokenExchangeRequest and compare it with tokenExchangeRequestWithAdditionalParameters. Confirm that additional parameters supplied to OIDAuthState can reach the token request for this workflow, including the JWT client-authentication case described in the issue.
