How to mount saved objects to kibana in kubernetes?

Question

I'm runnig EFK stack in my kubernetes cluster however each time i start kibana dashboard i will need to manually import export.ndjson i've heard that all kibana objects are stored in elasticsearch so a mounted this file to /usr/share/elasticsearch/data/ but still can't see it in the dashboard.

Here are my yaml files:

kibana :

apiVersion: apps/v1
kind: Deployment
metadata:
  name: kibana
  namespace: tools
spec:
  selector:
    matchLabels:
      app: kibana
  template:
    metadata:
      labels:
        app: kibana
    spec:       
      containers:
      - name: kibana
        image: docker.elastic.co/kibana/kibana:7.6.0
        ports:
        - containerPort: 5601
