ZStack on visionOS z-offset?

If I position multiple Model3D elements in a volumetric window's zstack, they are offset in space relative to each other (on the z-axis). If I want them all at the same level, is there a modifier I need to use?

Thanks!

it appears that the solution is to use a new variant of the frame modifier, .frame(depth: 0)

What if I want something to stick out though?
