Another way: you could say you always enjoy spending time with her and could be interested in her as more than a friend, and ask her if she has ever thought about that

But in some way that sounds natural to you. However, I wouldn’t recommend confessing in a dramatic way, or emphasizing that you’ve had a crush on her for a long time (if that’s the case), because those could accidentally feel pressuring

There’s not one perfect approach, but you could invite her to something and specifically say “…as a date”
