My crush is really introverted. How do I approach her without making her uncomfortable?

Hey r/crushes. So my crush is quite an introvert (she's not socially awkward or anxious, just not very outgoing) while I myself a bit more on the extraverted side. We already had some communication but it was not really in a casual hangout context, although I feel like we vibe pretty well and she also has an awesome sense of humor.

I'm basically paralyzed by a mixture of fear of rejection and fear of making her uncomfortable (and her being too nice by not showing it directly). I also don't wanna overwhelm her with too much social interaction. Give me some advice please😅

P.S. We're highschoolers if that's important.

TL;DR : My crush is introverted and I don't want to overwhelm her or be annoying. How do I make the first move?
