Any small gap the little hatchling can get it's head into will be access to a potential hiding spot.
Very likely under bed or under / behind something ( a walldrove or toy box ) , or even in the toybox and hiding inside a toy .
One place worth looking is the curtains if they drap to near the floor , hatchlings instinctively climb so check carefully the folds in the curtains.
One place I found a "lost" water skink ( was 15 g ) was curled up in the sleeve of my polo shirt while I was waring it , only discovered him there because I asked my wife to check the back of my shirt and there he was bold as brass and quite happy and comfy in his new "hammock" under my arm .
If you move furnishings , lift them don't drag them , it could be under and get injured.
Good luck. Most likely it's still in the room or maybe not far from that room and will turn up , esp if it's already pretty tame and people orientated.
If it not tamed or people orientated , it'll be hiding and will be harder to find but will come out eventually to find food.
If the room has a sunny aspect ( sun come in though a window ) , the sunny spot on the floor will be a draw to the hatchling.
If not, get a clamp lamp fitting and set up a basking spot under a chair or near a convenient table or fixture ( even a door nob ) , this will perhaps a draw the hatchling out .
