Introducing Formula for first time at 8 months

An

Does anyone have any tips/advice- My daughter is 8 months old- she stopped nursing around 6 months but I’ve continued to pump- however recently my supply has taken a major dip and I am running out of my freezer stash- I began to introduce formula for the first time but she just refuses to take the bottle screams/cries/turns away. Does anyone have any advice on how to transition her to formula or maybe someone else went through this. Thank you!
