How can I get my mouse to follow an AR image tracker?

Hi, I need to make it so that when I move around an AR image tracker, my mouse follows its location. I've seen some decent AR project built in Unity so I thought I would be able to just look it up real quick. The issue is that every search result I get is about making a game object follow a cursor, I need the cursor to follow the AR game object. I have just about no experience in coding, and I'm not asking for a full script, though I wouldn't mind if anyone helped me out. If anyone knows of a way for me to make the cursor follow the game object's location in screen that would be more than enough!
