Bezier cells for cylindrical meshes?

Are there any examples of using the new Bezier cells in VTK 9?/Can someone point me to examples/tests that show how to generate meshes with Bezier cells?

I have been trying to manually create them but it’s not going so well…

From an initial glance, this looks like it would now be possible to define 3D cylindrical meshes in VTK with the new Bezier Hexahedron cell - is that correct?

By cylindrical meshes, I mean meshes that include an azimuthal discretization from the center like this mesh from SimPEG's discretize package:
