Kubernetes MeshGatewayInstance does not support setting labels on the pod/deployment

We wants to filter/slice MeshGateway dataplanes by some custom labels set on the MeshGateway, eg:

apiVersion: kuma.io/v1alpha1

kind: MeshGatewayInstance

metadata:

name: public-mesh-gateway

namespace: kong-mesh-system

labels:

custom_label_1: local

spec:

replicas: 1

serviceType: NodePort

tags:

kuma.io/service: public-mesh-gateway

prometheus.io/scrape: "true"

prometheus.io/port: "5670"

prometheus.io/path: "/metrics"

Basically they need to add some custom labels to the pod definition of MeshGateway which is currently not supported from the MeshGatewayInstance Kubernetes CRD.
I tried to edit the deployment and then delete the pod, but there is no support for providing labels at the moment.
