Kibana rules - Is it anyhow possible to source document that was hit against rule?

Hi, as tittle says is it possible to gather document in kibana rule that was hit?

My usecase is like this that I am using inventory treshold rule for kubernetes pods to check memory usage treshold. I am ussing index connector and write it futher to index. I gathered full context object and it is missing pod name.
Is is possible to reach source document containing pod name?

Somewhere on internet I found syntax: {{.source.kubernetes.pod.name}} however in my case is null.

Just to confirm in document that is analyzed there is kubernetes.pod.name properly populated but I can't find any way to get it in rule writting to index.

@pmuellr /@ying.mao can we please get some help?

Thanks,
Bhavya
