Allow users to configure their own API keys so they con connect to their accounts for specific services accessed through current and future plug-ins:

API Key Configuration: A secure way for users to input their own API keys for various services used by the agent's plugins : Coinbase, OpenAI, Github.
* Security: API keys must be handled securely and should not be exposed in the client-side code. Consider using environment variables or a secure backend service for key management. Consider using the existing setting store in the database.
* Validation: The UI should validate the format of API keys and provide feedback to the user if invalid keys are entered.

This advanced mode should be a separate item in left menu and a form in the respective page that will allow users to enter and set keys and credentials for each listed service: Coinbase, Github, OpenAI.
