How to see gauge of AI Overview?

Edit: Sorry, meant to write 'gauge impact' in the title I'm new here. I've run an informational site related to a popular IP/Franchise for several years now, and this year has had the strangest traffic development I've ever seen, with a \~50% drop in both organic search and direct traffic, all in a few months. I know that this is the year that AI Overview started rolling out widely, and I'm trying to gauge if there's some way to see just how much traffic for some of the keywords I rank highly on -- my ranking hasn't really changed in any of them according to Search Console -- is being responded to by AI Overview and not leading to clicks through to my own site. Is that something that can be seen somehow? I can post some analytics traffic charts and the like. I did get a very sudden \~40% drop in early May of this year that Analytics even claimed was an anomaly but I wonder if that's some sort of error with my Analytics setup, because I've another server-side analytics package through my ad tech that shows no drop in traffic then. But for sure, these last few months traffic has dropped sharply. (I really am not an expert at any of this, it's half a hobby and I've usually just trusted guides and such. Are there people who can be hired to audit, look over analytics and google search, make sure there's no obvious mistakes at play? Is there a term for someone who can do that that I can look up?)
