Microsoft Copilot (Microsoft 365): Support for MCP Agents with Interactive UI Widgets in Government Clouds

Feature description: Model Context Protocol (MCP) based agents in Microsoft 365 Copilot Chat will now be able to surface rich, interactive UI widgets directly within chat. This enhancement enables developers to deliver more engaging and structured agent interactions. Users will experience these widgets when interacting with agents that implement them, and admins will continue to manage these agents through the Microsoft 365 Admin Center.
