Question:
How to merge configs using KubernetesClient library and save them into config file?

Description:
I have used LoadKubeConfigAsnyc() to load the config sent from the frontend, but I need to merge them into the existing config file. But there is no public MergeKubeConfig() method and SaveKubeConfigToFile() method in KubernetesClientConfig class. How to achieve this? thanks.

Program operating environment:
Docker Container
