How to find nodepool name from node in AKS

My requirement is to fetch the nodepool name from the node in AKS cluster.

I have been fetching nodepool name as agentPool name (given in below output response) but it seems to be incorrect.

What is the correct way to fetch the nodepool name for the corresponding node?

kubectl describe node aks-customName-234234234-vmss00011

I donot see any attribute which matches the nodepool name. This is already running cluster and I have node informations as below for each node and nodepool list.

I need to group these nodes to the nodepool.
