Zeebe-simple-monitor is not able to connect to hazelcast

[kalesujata97]

We used this helm chart to deploy zeebe-simple-monitor on kubernetes. Already we have zeebe-cluster(zeebe broker + gateway) on same kubernetes cluster. So we need to mention the brokerContactPoint and hazelcast url in zeebe-simple-monitor.
Can anyone guide us on environment variables which we can specify in simple-monitor so simple-monitor can communicate with broker and hazelcast.

More details:
Currently we are using below environment variables:

env:
   - name: ZEEBE_BROKER_CLUSTER_CONTACTPOINT
     value: zeebe-zeebe-gateway:26500
   - name: ZEEBE_WORKER_HAZELCAST_CONNECTION
     value: zeebe-zeebe-gateway:5701
