To call Ansible legacy module from within library's custom module

[Leo Y]

I would like to use existing implementations while developing a custom module. For this matter, I want to use k8s_raw module to communicate with Kubernetes cluster instead of importing python packages and managing the whole logic.

How can I call an Ansible legacy module, for example a `k8s_raw` from python code of the custom library module?

Thank you,
