How to I get her to stop playing hard to get and admit she’s interested?

Been talking to a girl on instagram DM’s and we’ve been talking for a little while and she replies pretty quickly within 1 or 2 minutes each time I send her a message and occasionally might take an hour to see my message but doesn’t reply to every message I send so I think she may be playing hard to get. uses extended haha’s a bit so I asked her if I could ask her a question but forgot to reply so she sent a couple of question marks a couple of hours later which makes me feel like she’s chasing me a little bit, her responses are usually sort so I asked her we were in a talking stage but she didn’t reply, she’s viewed a few of my instagram stories after I’ve sent her a message. So I also asked her if she’s usually this quiet or is just me and she said she’s not much of a talker. So what I do about her playing hard to get if that is what’s happening?
