Creating reflections on cabinets and other surfaces in HDPro19

[NivRajan]

Hi, I'm trying to get my renders to look a little more realistic by adding reflections, as the Pro renders look really flat. I read another tip as to how to get my floors to look shiny by adding a mirror below a transparent top surface, which really helped. I need a workaround, if any, to get the same effect on my cabinet doors too.
Thank you!
