Assessment Reasoning
The feature change introduces a new navigation method for accessing Copilot agents in Excel. Admin controls and licensing remain unchanged, and there is no impact on workbook editing or data permissions. Minimal admin effort is needed to inform helpdesk and update training materials, but the user experience changes as the access point for additional agents moves to the header menu.
