How to get baby used to the breast again?

Hello, I gave birth less than a week ago, and in the hospital, I was immediately told to give my baby formula because she'd lost weight and to pump my breast milk at the same time to stimulate milk production. The pediatrician later told me that some weight loss is completely normal.

The problem now is that my baby got used to the bottle relatively quickly, and I need some advice on how to get her to accept my breast again. My baby sucks a few times and then always starts crying until I give her my expressed milk again. My baby also doesn't suck as hard as she did after birth, probably because the milk is practically dripping out of the bottle and you barely have to suckle.

Thanks in advance for the answers
