Tell her that you like her. you'll know her reaction by default.
go and straight forward tell her whatever be her reaction doesn't matters yes or no doesn't matters if yes enjoy if no find another
Sometimes we're so worried and afraid of these small things and it's okay! Remind yourself that this girl is also a person and there's nothing to be afraid of or intimidated by. Don't overthink about it too much, just tell her! Be confident and direct, if she sees you as a date, that's a win, but if she doesn't, it's also a win, because it means that you guys weren't meant to be and there is someone out there for you. I wish you the best of lucks!
