Why Does A Calendar Event/Invite show unrelated files next to the lightbulb?

I accepted a calendar invite, and then upon double checking the meeting time, I saw that the header contained a series of prompts/summary including a file next to a lightbulb.

I panicked since this file contained sensitive and confidential information not pertaining to anyone or anything related to this company or meeting, and was private and personal financial information of mine and a client's from a separate business.

I checked around on the internet and saw (from a third party website since all of the outlook/microsoft website suggestions on this forum were out of date and not pertaining to this feature) that this is a suggestion from AI mining/scanning all of my recent files that it thinks are appropriate or relevant for this meeting, and that only I can see it. Thank goodness for that! I have a habit of accidentally attaching or forgetting to attach things to emails so I thought it had been my fault. To find out it's supposedly a useful and helpful feature is laughable.

But my question is, why can't I seem to customise or remove this, why is it doing this without my permission, and if it can be done, how in the world do I turn it off? And if I can't turn it off, please give us the option to turn it off immediately. Stop chucking AI and suggestions into everything, we don't want them.

More broadly, microsoft why do you keep changing outlook to be less useful, less accessible, and less functional? It's a task to even locate the attach file button anymore. I don't see anything in my settings that even refers to this ludicrous event/calendar invite/meeting summary header let alone its suggested file attachments/recent files, I've double and triple checked every setting in general, email, calendar, advanced options, and combed through several forum questions from years ago that are no longer relevant just in case they hid a trace of a setting somewhere. But no, nothing. My job is to be a researcher, teacher, and generally functional employee. Not to learn the ins and outs of microsoft's latest AI and GUI updates for hours at a time.

Please help.
