Hello,
I've created a Copilot agent on Microsoft 365 and used a SharePoint site as a knowledge source. Initially, it worked perfectly for users who had access to the site by answering questions using the information in the documents in the site. However, after changing the permissions on the SharePoint site to restrict access, the Copilot agent is still providing responses to users  by referencing the same documents even though user access has been removed from the site and the documents.
Despite these efforts, the issue persists. Could anyone provide insights or solutions to ensure the Copilot agent respects the updated SharePoint permissions?
Thank you!
