From a technical standpoint, this is exemplified in a tutorial: https://docs.quantumwise.com/tutorials/optical/optical.html#optical-spectrum. However, from a physical standpoint, I am not sure the Kubo-Greenwood optical spectrum is valid for 2D materials. As far as I know, the KB optical spectrum is mostly applicable to 3D bulks.
