Facing issues in Metric format to replicate query from Grafana to KIBANA

Hello,

I am trying to replicate the below query from prometheus GRFANA to KIBANA.
I am not able to get same results, not even close.

sum(node_namespace_pod_container:container_cpu_usage_seconds_total:sum_irate{namespace="assurance"}) / sum(kube_pod_container_resource_requests{namespace="assurance", resource="cpu"}).

i am using metric format.
