How am I installing JUST Black Ops 6?

Hi,

I was hoping someone here could help...

I wanna install Black Ops 6, but ONLY Black Ops 6, if that makes sense?

I don't want/care about MW2 or 3. I really don't care for Warzone either. I'd just like to ideally install and play the new CoD, if I can.

When I go on the menu to install the different parts, it's a bit confusing.

Can anyone help, and just tell me what I need for what I want?

Thank you!
