How do I stop standing around awkwardly?

Pretty much what the title says. I’ve gotten so much better in the social department. But there’s this one annoying problem I can’t seem to figure out. It’s when I’m standing around waiting for someone, or for someone to acknowledge me, or anything where I have to wait while others are present I’m so so awkward. Looking around, being hyper aware of what my body is doing, trying not to look at any specific person a creepy amount, pretending to check my phone… Wtf do other people do while they’re standing around because I feel like I never see other people doing all that.
