Connecting my wife to my health insurance

Hello, I'm coming from Serbia and currently working in france. I have my titre de séjour and covered also health insurance wise. My wife is also from Serbia and she just received autorisation provisoire de séjour. She is pregnant right now, so I would like to connect her to my health insurance so we don't have to pay for delivering a baby in the hospital. Can someone help what I'm supposed to do?
Thank you very much
