Need help: How to transition baby from breastfeeding to bottle feeding

Need help 🥲 I have 20days old baby who is breastfed since birth. I will have to attend my toddler's school on Monday and till now, my baby doesn't know how to bottlefeed. So far I have tried comotomo bottle. Yesterday and today I tried to feed her using the bottle but no luck. She just kept on crying till I gave up and gave my nipples to her. Help mommies 🙏😭 What else can I do?
