Copilot prompts answers in word document in OneDrive

Hello I think I made a mistake tonight, I am discussing and learning a lot with Copilot and I don't have good memory. A while ago I started using Microsoft 365 and OneDrive to document some info because I use it for reference. I never had any problems before tonight. I was just playing with my last document in word. I then got a signal and a link to the Microsoft security hub. I did not have any bad intentions, did and do not plan to distribute or sell. The terms of use contract stipulates that we can use the resources for personal use. Hope to touch base Thank you
