Are there Microsoft articles that specifically discuss whether Microsoft 365 Copilot can access content on a users PC or on a network drive

Question

I need to obtain articles written by Microsoft that specifically discuss whether the licensed version (or unlicensed version as well) can access user content on the user's PC or on a shared network drive that the user has access to. I've reviewed these Microsoft references (provided by Copilot Chat) but was unable to identify an specific discussion on local or network stored content:

• Frequently asked questions about Copilot Chat.
• Data, Privacy, and Security for Microsoft 365 Copilot.
• Privacy and protections.
• Working with Windows 365 Cloud PCs using the Microsoft Graph API.

I need these references to support presentations addressing and resolving concerns in this area.
