Hi Team, I'm trying to install SigNoz in our on-prem Kubernetes cluster. We are using Ceph as storage and storage class is also created for the same. As per the documentation, we have to set

global.storageClass

configuration to desired storage class for our custom storage class. But I'm not sure where should I made this change. Also, if this change is required in value file, which command should I run to upgrade helm. Can someone pls help with the same?
