Donating placenta/umbilical cord


Does anyone know anything on how to donate your placenta AND umbilical cord? Like the process? Does it cost (I was told it did which is confusing to me.. why do I have to pay to give someone who is in need of something ?) or just know anything at all?? I didn’t get the chance to ask with my first child by the time I thought about it she was here (came early!)

I’m going to ask my dr next time I go of course just wanted to hear from others in advanced
