Can I preview a personalized experience on my Hydrogen storefront before publishing?

Before my team publishes a new hero experience, our stakeholders want to see it live on the actual storefront, in the right colour and layout, not just in the editor preview. We have a proper review step and people want to click around the real Hydrogen pages first.

How does preview work for this, and what needs to be set up for it to show the personalized version rather than the default one?
