If third party tokens are not enabled, you should add the option

If the <code>jwtPolicy</code> is not set correctly, pods associated with <code>istiod</code>,
gateways or workloads with injected Envoy proxies will not get deployed due

Operator to Helm, you need to delete your current Istio control plane resources
and and re-install Istio using Helm as described above. When deleting your
current Istio installation, you must not remove the Istio Custom Resource
Definitions (CRDs) as that can lead to loss of your custom Istio resources.</p><div><aside class="callout warning"><div class=type><svg class="large-icon"><use xlink:href="/v1.9/img/icons.svg#callout-warning"/></svg></div><div class=content>It is highly recommended to take a backup of your Istio resources using steps
