Helm isn't that connected to the broader Kubernetes system. It was popular in the early days when Kubernetes knowledge was sparse and things were still being figured out. None of the official Kubernetes docs really mention or describe using helm, and I see more getting started tutorials are starting to avoid it too. The official kubectl tool supports a -k mode which applies Kustomize logic and I'd argue Kustomize is probably the official way forward with app deployments by the Kubernetes project.
