Kommander uses several custom resource types that won't be displayed if you run "kubectl get all". This includes resource types like "helmrelease" or "kustomization".
If you'd like to list them all, you can run the following:
kubectl api-resources --verbs=list --namespaced -o name | xargs -n 1 kubectl get --show-kind --ignore-not-found -n kommander
This can be used for other namespaces as well; simply replace "kommander" with the namespace you would like to list.
