Free Apple TV+ free for a year because of my purchase but I don't have an Apple box

So, I recently bought a new laptop from Apple. It offered me free Apple TV+ free for a year because of my purchase but I don't have an apple box. I know I can use it on apps while using any of my apple products but I would like to know how I would go about watching it on my tv. Do I need the box?
