Labelling newly created faces in gmsh and dolfinX

Hi All,

I am trying to create a mesh which is basically a cube with a small region cut out of it in gmsh python. I have figured out how to cut out the small region (currently a smaller cube, but will later be a more complex shape), but I need to know how to define the faces in the new cut out surface region of the cube. Has anyone got any experience with this?
