Measuring reaction to detection


I want to know whether there is a functionality in Elastic Security to monitor reaction time to detection for example to count SLA. Is there smth called internal index from which I can get fields that will show me when my detection has been created and closed? And after that to build a dashboard based on reaction speed

Btw, can I escalate an alert to another analyst? Or mark it as false positive. Unfortunately, I haven't found such buttons

Not sure if that is built in feature yet, anyone from ELK can respond?

So here is what I do for our clients when it comes to using Elastic SIEM and ensuring SLA:

You can see if someone already has requested this feature in Github. And if you don't find anything, then you should request it.

Thank you for your advice!
