I was looking into how OIDC authentication for Kubernetes clusters is handled by the plugin, and some aspects are not clear to me. As I understand it, a temporary kubeconfig.yaml file is created when the Backstage backend plugin starts. This file is then populated with user tokens through refreshKubeconfig requests from the frontend plugin. My question is: how does this work in the case of multiple users? Is there something that prevents OIDC tokens from being shared between different users? Or am I misunderstanding something? Thank you!
