Answer
The middle tier runs as a containerized Kubernetes deployment (typically via a lightweight distribution like MicroK8s) rather than as files laid out in a traditional directory tree, so don't expect to find application code sitting in a browsable folder the way older on-premise installs worked — configuration is managed centrally and pushed in as part of deployment, while the running components live as container images and cluster state rather than as ordinary files on disk. Use the cluster's own tooling (checking pod status and logs) to inspect what's actually running, rather than searching the filesystem for it.
