Is this toxic/narcissistic behavior?

Okay I need honest advice for this one.

My classmate held a speech in front of my class and I checked my phone for a moment but still listened to her. Then she yelled at me to pay attention to her in front of the whole class and I responded annoyed. Later, I wanted to confront her about it but she said that she didn’t had to talk about it because she saw no problem in her behavior. I ignore her now but I ask myself if this is toxic or narcissistic behavior?

P. S. The funniest part is that she‘s mostly on her Ipad or phone when someone else or the teacher is talking but still dares to belittle everyone else on this behavior.
