Inverted flat nipple - cannot breastfeed bb

Hi mummies, anyone managed to still latch and breastfeed baby(not pump) when they have inverted or flat nipple? I dont need product recommendations or shopee links cause ive heard about nipple puller and nipple shield. After i gave birth, the nurses told me i have inverted and flat nipple both sides therefore i will not be able to breastfeed baby and can only pump. So just wondering if any mummies actually managed to latch baby and how do you do it ?
