Which cabinet item should I use?

Use the gray bottle opener/pliers-like tool on the lower shelf; the scissors on the upper shelf are a decoy.

Drag it from the lower shelf to the cap on the patterned bottle in the center of the machine platform.

Should I operate the gray machine arms myself?

No. The placed opener lets the machine complete the cap removal; direct arm attempts fail.

Yes. Once the bottle opener loosens the cap, the machine finishes the job automatically.

If the player asks you to sign in, open the video on YouTube instead.

Tap the right-hand cabinet door to open it.
Select the gray bottle opener/pliers-like tool on the lower shelf.
Drag that tool from the lower shelf onto the bottle cap on the central platform.
Do not move the scissors from the upper shelf; wait as the machine presses and the cap pops off.
Confirm the green check and the dialogue success page.

Colors in this level:

White, Gray, Red, Black, Teal, Yellow

Tapping or dragging the hanging machine heads directly produces the red X.
Trying the upper-shelf scissors does not open the bottle.
Moving the bottle without placing the lower-shelf tool on its cap leaves the cap closed.
Stopping after opening the cabinet misses the final machine action.

Open the cabinet on the right.
Use the gray bottle opener/pliers-like tool from the lower shelf, not the scissors.
Place the tool over the bottle cap and wait for the machine to finish.

Danger Zone: The machine arms and Doctor's black tray are not the tool; the upper-shelf scissors are a decoy.
