Lens Studio Shader Missing

I'm making some 3d asstet for a snapchat filter the texture when impoted into snapchat appeats alot darker than when it was in substance painter. I looked at the lens studio documnation for textureind and saw that substance painter had an lens studio shader. I look for the shader in substance painter and it was missing.

The lens studio documentaiton doesnt say how to get the shader just shows how to select it in painter.

Was it taken out or do I have the do something to get that shader?
