What part(s) of the content would you like to see updated?

I try to deploy the helm chart with default value for scaleway-cilium-hubble. After the deployement of the hubble resources (deployment, config-map, ...), and before performing a roll-out restart of cilium agent, i get an error. The pod hubble-relay is in crash loop-back because the startup probe failed. The pod report a connection refused error:

time="2026-04-23T09:29:44.562563869Z" level=info msg="Failed to create peer notify client for peers change notification; will try again after the timeout has expired" connection timeout=30s error="rpc error: code = Unavailable desc = connection error: desc = \"transport: Error while dialing: dial tcp 10.32.15.118:443: connect: connection refused\"" subsys=hubble-relay

Due to the fact that cilium.agent is set to false, the cilium config maps is not modify. The currently deployed config map cilium-config in the kube-system namespace, still shows:
enable-hubble: "false"

And this could cause the connection error.

So, I think there is something missing in the doc.

If the pod error is normal, then it should be mentionned after the helm update command.
