For PCV, a little bit confused on this - does the Product List Page (/results) automatically inherit the setup of the PCV configuration designed for the specified customer group or do I need to setup a Commerce Category? TIA!

The items do need to be part of that category to be displayed, but PCV will hide or show based on its settings

I am under the impression based from the docs that I do not need the items to be part of category, as I am using Item Collections to trigger the PCV, unless I am missing something here.
