My manager switched me to another area without asking

During my end of my year review, my supervisor announced that they were bringing me along to a new area within my department that they are going to lead. They said it’s a good opportunity for me since I will help them lead this new team but they never discussed this opportunity or asked me if I even wanted this. I’m good where I am and don’t want to go through this change. I feel like I have no control over my own career lol
