New Copilot button in file previewer for OneDrive and SharePoint [MC1182707]

Message ID: MC1182707

[Introduction]

We’ve added a new Copilot button that gives users a quick and visible entry point to Copilot directly within the file previewer in OneDrive and SharePoint. This button appears near the bottom-right corner of the file previewer (instead of in the command bar) and surfaces contextual prompts for Copilot-supported file types. It also provides access to the Copilot chat.

This message is associated with Roadmap ID 513432.
