Boob to bottle??

So My daughters ebf since birth, and in April I’ll be starting uni ounce a week and I’ll need someone to look after her for a few hours. But she won’t take a bottle 🙄 I’ve even gone out of the room for half an hour and my brother said she’d still won’t take it. She’ll just lay there and chew on it looking confused about what it is. We’ve only tried avent bottles so far, but the teat seems to be way bigger than my actually nipple, so she might not like it 😂 but we’ve also tried sippy cups too. Any suggestions on how I can get her to take a bottle? Or any recommendations on which bottles are best?
