[Gmsh] Gmsh OCC class Physical Groups

Hi,

Hope everything is good. I'm working merging two meshes into one via the
.cut OCC class method, but my output has all the Physical Groups defined as
0, even when adding a PhysicalGroup to the model. Here's a quick example.

gmsh.model .occ.addPlaneSurface([-(12 + i)], i + 2 + 100)
gmsh.model.addPhysicalGroup(2, [i + 2 + 100], i + 2 + 100)

When I open the meshes all of the surfaces have the same PhysicalGorup
index. Is there a way to use the OCC class and set Physical Groups as it
can be done using the geo class?

Thanks!
