How to set up Amazon Attribution if I’m just making a link to the whole store?

I’m getting a bit confused here and haven’t found the answer elsewhere online. I’m not currently running external ads, but have a link to my store on my instagram profile. I’d like to replace that link with an amazon attribution link. I see in the amazon attribution campaign where to set that up, but I’m confused about what I’m supposed to pick for the products since I’m not advertising any specific one of my products. Do I pick all? None?
