Samsung Cloud Upgrade?

[Tuesdaynite]

Hi, does anyone know how to purchase additional cloud storage from Samsung on Galaxy S8 Plus? I have looked in my phone, on Samsung's website, and the rest of the web but can't find out how to buy cloud storage for my specific phone. The instructions I've found are only for other models. (I did find one instruction for S8 & Plus but the screen captures do not match what I see on my phone under the settings described.) Thanks!

Settings cloud accounts somewhere in there, sorry don't remember exactly
