bb.showliveeditobjects
type debug on text search and click one of those debugs with stars

you can also categorize them by the pack once you have the debug open to make things easier to find

basically bb.showhiddenobjects is for all the hidden objects that might have some gameplay use or be used by sims during animations or whatnot

bb.showliveeditobjects is for the decorative objects out in the world landscaping houses so forth

but yeah you have to text search debug after the cheat
