Hello,

I have a terms aggregation with 2 metrics, where I want to alert only on terms if `metric1 > metric2`  
So, basically it involves iterating over the array `ctx.results[0].hits.hits` and checking the condition for each term.  
When creating Trigger, I can iterate through this array and return true if atleast 1 such term exists.  
But, when sending alert (Action), I only want to list terms which have met the trigger condition and not all the terms. I see that mustache templates can be used inside Action, but how can I filter the terms that met condition?

I see my situation is little bit similar to [this post](https://forum.opensearch.org/t/if-else-in-trigger-action/469) which says there is no way to do it using mustache. But, just checking if anything changed since then or if there is any alternate approach I could take.
