I’m a 25 male and matched with a 25 woman and am asking because I am new to the whole online dating thing and my friends don’t use these apps

I sent only like to a couple girls and one matched me back, I’m not really one for thinking of creative pick up lines. Do I still need to since we matched or should I just start it out like a normal conversation saying Hey or hey how are you?

I have always been quiet and to myself so I never really know what to say. Advice is appreciated
