How do I stop my Mac Mini from asking me to log in to FaceTime?

We live in a house that uses predominantly Apple computers and, for the whole time that I've been using my Mac Mini (I just updated to the 2024 model), it keeps asking me to log into my mother's account to use Facetime, and the only options available to me are to cancel (in which case it will just ask me again in a few days), or to log into my mother's account. What it doesn't give me is an option to click "Never"; I'd like to click "Never", I never want to use FaceTime, and I never want to connect my computer to my mother's account. How do I stop my computer from asking me to use FaceTime?
