I've seen some super misleading videos about what each icon (classification) means, so this is how the code behind my own game review works. Remember that my classifier does not work in exactly the same way as Chess.com's! This is a video on how move classification works generally speaking. Plenty of other websites, Lichess included, have move classifiers.

notes:
sorry for my rubbish microphone, i'm not at home right now ;(
i did not use AI to make any part of the game review
anyone who ignores the video entirely and comments about chess.com apparently being the only entity who can say what icon a move is given, is an idiot and has never heard of lichess
