How to make a move on a guy over instagram?

I’m 15 years old and I think this guy is cute, for context he was in one of my classes last semester and we have never spoken before.
I’ve had my eye on him for a little while and today I requested his spam account and got in! Whenever I talk to guys, I always fail at it, I’ve never had a boyfriend or many talking stages. How do I text him first? Or how do I make him text me first? For now I just want to be friends with him. What do I say?
