How to approach a girl that I like and the feeling is mutual

I’m a M22 and I’ve been texting this woman F23 for a minute and every time we text it’s very flirty and all that. Tonight we are going out with a group of friends and she’s expecting me to make some type of move at the bar but I’m inexperienced when it comes to this stuff. How do I start making advancements with her being comfortable and her feeling the energy and reciprocating back?
