A new kubectl secret control-panel-azure was applied manually using kubectl --namespace cpanel apply -f secret.yaml.

@jamesstottmoj also tried to add a new secret in the old method, via Flux, however this failed to update the secret.

TODO
Need to release a new version of the helm chart that also adds the AZURE_CLIENT_SECRET env var
