Guidance on Enabling SharePoint List CRUD Operations via Declarative Copilot Agent

Question

I have a working declarative Copilot agent with several functionalities already implemented. I’m now looking to extend it by integrating SharePoint functionality — specifically, I want the agent to:

Send data to a SharePoint list

Retrieve data from the list

Perform basic CRUD operations (Create, Read, Update, Delete)

I'm looking for official documentation or best practices that outline how to enable this within a declarative agent setup. In particular, I'm unsure of the steps involved in securely performing these operations through Microsoft Graph using delegated permissions and whether any special configuration is required in the Teams Developer Portal, Entra ID, or plugin manifest.

Could anyone point me to relevant documentation or samples or guide how to approach this integration?

Thanks, and my regards!
