How can I get rid of jaundice? Pls help!!!

At my baby’s 5 day check up the doctor told me she has a bit of jaundice in her face and to put her in the sun. Well there is literally zero sun where I live, it’s rainy and cloudy all day long. I give her vitamin d drops but I don’t think that’s the same. So how can I get rid of her jaundice if there’s no sun??
