Is there a way to expose only some agents to the front end with CopilotKit integration?
https://mastra.ai/ja/docs/frameworks/copilotkit This document adds a copilotkit endpoint to the Mastra server. In my use case, I add the copilotkit endpoint to the BFF with the mastra server as the backend and call it from the frontend. When adding the copilotkit endpoint in BFF I do not want to expose all the agents implemented in the backend.
