Research direction

Investigate the OAuth2 client settings configuration in the NSwag middleware, specifically how the ClientId is passed during the password flow. Look at the SwaggerUiSettings class and the OAuth2ClientSettings handling. Review related files in the NSwag.SwaggerUi or NSwag.AspNetCore namespaces. The issue may require modifying the JavaScript that handles the OAuth2 password flow to include the client id parameter in the token request.
