"Ask Copilot" in Windows Explorer context menu

On both my work and personal laptops (Windows 10 and 11), I have noticed that the file context menu in Windows Explorer now includes an "Ask Copilot" option.

I have privacy and security concerns about that. If I accidentally select this option, will the file or its contents potentially be uploaded to the web somewhere? Will Microsoft use the contents of the file for other purposes? I didn't find clear answers on that. If I wanted Copilot to analyze a file, I would prefer to select the file thru other means. I don't need extra items in my context menu; it is already lengthy due to other custom entries (which I actually use on a frequent basis) that I've added to it. So I will edit my registry to remove the entry from the menu.
