Hello everyone, I have some questions about system design related to Ory. We are trying to integrate Ory for authentication and authorization. Currently, we have an app-router Next.js project that serves the web interface for user. The Next.js server-side code needs to communicate with a gRPC API, and we handle business logic and access control there. But the problem is that Next.js only has session cookie, how can it pass the authentication information to the gRPC service?
