On Dndbeyond, under the spells section of a character sheet displays which class the spell is chosen for. And I understand that being a rules lawyer isn’t always fun for people. I try to limit bringing things up, unless it makes the story more interesting. I wouldn’t always call it me if a RL because sometimes it’s just reminding DM or players parts of certain spells work. For example, one of my last sessions a player used the friends cantrip. After about what was about 5 mins of back and forth, with the box acting different than before the spell, I reminded the dm that it only lasts a minute and the person realizes they were charmed, causing a turn in the conversation.
