central exhibition missing furniture

[「GOLD EXPERIENCE」]

OK I've been trying to find the 1 last damn furniture in the central exhibition in the museum but I cant find any. this is the furniture I remember I fixed:
1. the whole T rex fossil (arm, clavicle, jaw, 2 tails, femur and toes) and the smaller T rex statue
2. the fire extinguisher
3. the paintings in the front (all filled), the painting near the yellow door and the pterodactyl(?) fossil painting display thing
4. the third egg and the feather statue
5. the sofas and the fallen display

can anyone let me know what I miss. this stage is frustrating me. I kept spamming Q but I cant find any blue hologram

if you're really stuck, wemod has a cheat that allows for putting the furniture away automatically by just picking it up and putting it down. I remember though there's a statue on top of the floating tables. Also a donut on top of the glass containers in the music room that looks like a balloon.

OK so I apparently decided to gave up on that 1 furniture and do the rest of the stage. apparently SOMEHOW the yellow cabinet in the yellow room is considered to be in the central exhibition area. just letting people know.
