How do you get artwork underneath Clear Sanwas?

I see answers and tutorials for the Seimitsu buttons but not for Sanwas. I’ve gotten the button off, but the clear part and white part are still together.

Bump

I’d like to know as well.

The plunger has 3 parts to it the clear outer shell, a flat white disc and the x shaped plastic piece that holds the disc in tight with a groove for the white tab of the microswitch to fit in that X part just snaps out its really simple then remove the little white disc to put you circular art in the button.

Got it. Thanks!
