OpenSearch - Mount PVC

Hi Team,

I want to modify the open search yaml file such that it mounts the data in a persistent storage .
This is the yaml file - https://github.com/opensearch-project/helm-charts/blob/main/charts/opensearch/values.yaml

I have created a persistent volume storage, and I just need to add it to this yaml file , but do not know where to add - Please help.
