This is the same as a bit of classroom management advice I got when I was learning to teach. If you plausible didn’t notice something you can ignore it if you want to, but if the students know that you know something happened then you have to respond.
For example, maybe students aren’t supposed to use their phones during class, but so many students try to sneak in a text or something that you’d be stopping the lesson every 5 minutes to fuss at a student (and excess fussing can make you seem ineffectual at enforcing the rules because people keep ignoring you). So you can do things to prevent yourself from noticing students playing on their phones. When you notice you’ll have to act, but if you keep your back turned to them while you write on the board, look away from where the student whose on their phone is, etc. then you don’t have to respond every time. You can still respond often enough that it’s clear the rule is in force, but not so often that you can’t get on with teaching while one student ignores you.
