A Problem of showing up the metal effect in AR(USDZ)

[HAEJIN5E99]

I want to show up 'Glass Visor' material which has Metalic100%, Roughness0% and has a little bit of gray color like "mirror".

But when I excute an export as usdz and show up into smartphone, it has not like mirror as working in Adobe substance painter.

How should I make this material same as working in working in Adobe substance painter?
