Technically you can do it anywhere, here it is in the Player Character. Create the widget (and store its reference) and do the trace there to retrieve the reference of the world object.
In order to keep it as simple as it gets, I created text variables in both the widget and the object and called it *FurnitureType *and the rest happens in the player character:
This can be, obviously, vastly improved but should work as is for something straightforward.
