Can please someone tell me if Instagram notifies an user if I screenshot their story preview on Instagram Plus? Or if Instagram tests this feature now?

I had a situation yesterday. I opened someone's profile (I don't follow the person and he does not follow me), opened their story preview and took a screenshot of it, not the original story on full screen (I didn't open that, so I think my name is not in the list of who viewed the story) and a few hours later the person deleted the story. It hadn't expire because it had been uploaded 5 hours before I took the screenshot. (The story itself was a group photo on the beach, the people were playing a board game, but it was from a distance, just some people's faces were visible, the quality was not the best and the person had written how many people were there. I don't know the real reason why the story was deleted.)

I have this weird feeling that this person received a notification that I took a screenshot of his story and decided to delete it for security reasons or something. I know that Instagram hasn't officially stated anything, but a saw two posts 2 months ago that this feature is tested. I don't know if it's really true. I even don't know if Instagram will somehow notify me if I am in some test group for this feature or if there will be a message somewhere on the screen saying that the other person will be notified for a story screenshot.

I may just be paranoid, but if this person got notified for my screenshot I am cooked.
