[Service-mesh]: Unable to apply MeshTrafficPermission

Hi,
I just tried to implement MTLS in service-mesh. I used below link to follow the instructions.

When I tried to add a policy, I am getting below error while applying the policy.

apiVersion: kuma.io/v1alpha1
kind: MeshTrafficPermission
metadata:
namespace: kong-mesh-system
name: mtp
spec:
targetRef:
kind: Mesh
from:
- targetRef:
kind: Mesh
default:
action: Allow

kubectl apply -f meshtrafficpermissiononmeshca1.yaml
error: resource mapping not found for name: “demo-app” namespace: “kong-mesh-system” from “meshtrafficpermissiononmeshca1.yaml”: no matches for kind “MeshTrafficPermission” in version “kuma.io/v1alpha1

Please suggest what is the issue.
I am using:
Minikube
Zone CP version: 2.7.4
Type: Kubernetes
mTLS: builtin / ca-1

Hi! Can you send the output of kubectl get crd | grep -i kuma please? Also any details / configuration on how you installed Kong Mesh (via helm, via kumactl, etc…)
