need help transitioning to milk

my daughter just turned 1 and i think my milk supply is gone. i was planning on stopping breastfeeding anyway but now that she’s not getting anything i feel more pressure. the problem is, she has been ebf, never drank from a bottle before. i’ve tried to give her water in a bottle and she just chews on it. i’ve tried bottles with straws and same thing. how do i transition her to drinking milk if she doesn’t know how? and how much is she supposed to have and how often? i feel so bad i feel like she’s so hungry and she tries to nurse and she’s still upset afterwards
