Haakaa?

So I didn’t get one with my first but was looking at maybe doing it this time? I get it catches the milk from the other boob while baby is feeding from the other but what do you do after you’ve collected it? Does that mean I need to buy bottles too? What if baby doesn’t take to a bottle? How do you store the milk and how do you use it/heat it up? I just exclusively breastfed my first so I have no idea how that all works. Thanks I’m advance!
