What do I need to do to my Hyacinth (if anything)?

I don’t know anything about plants but this plant is important to me and I really want ti keep her alive. I don’t know plant language or anything like that so please excuse me. This is a store bought hyacinth and it was in bloom when she was gifted to me. I read that as it started dying I was supposed to cut off the flowers and I did that. I have been trying to keep it watered by using a spray bottle to keep the soil moist but not soaking wet (although at first I did just have to pour water because I didn’t have a spray bottle). She is still in the store bought pot, I keep her on the windowsill to get some light but I don’t open my blinds. I bought a plant lamp but haven’t used it yet but bought it just in case (I don’t open these blinds), I keep her indoors and do not have the option of planting her outside. I don’t know what I need to do now. Any help is appreciated.
