Add secret to projected list volume kustomize

Question

I am trying to use kustomize to patch existing Deployment by adding environment secrets in the list of projected

deployment.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  labels:
    app: microservice-1
  name: microservice-1
spec:
  selector:
    matchLabels:
      app: microservice-1
  template:
    metadata:
      labels:
        app: microservice-1
    spec:
      containers:
        image: URL
        imagePullPolicy: Always
        name: microservice-1
        ports:
        - containerPort: 80
          name: http
        volumeMounts:
        - mountPath: /config/secrets
          name: files
          readOnly: true
      imagePullSecrets:
      - name: image-pull-secret
      restartPolicy: Always
      volumes:
      - name: files
        projected:
          sources:
          - secret:
              name: my-secret-1
          - secret:
              name: my-secret-2

patch.yaml

- op: add
  path: /spec/template/spec/volumes/0/projected/sources/0
  value: 
    secret: "my-new-secret"

kustomization.yaml

apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization
patchesJson6902:
- target:
    version: v1
    kind: Deployment  
    name: microservice-1
  path: patch.yaml

Error

Error: updating name reference in 'spec/template/spec/volumes/projected/sources/secret/name' field of 'Deployment.v1.apps/microservice-1.itc-microservices': considering field 'spec/template/spec/volumes/projected/sources/secret/name' of object Deployment.v1.apps/ms-pedigree.itc-microservices: visit traversal on path: [projected sources secret name]: visit traversal on path: [secret name]: expected sequence or mapping no

How can I add new secret to the list with key secret and field name:

- secret
    name: "my-new-secret" 

NB: I have tried to to a PatchStrategic merge but the list is all remplaced.
