Hello
I have a field called reviewers in my tickets. To create this one I'm using the Jira field people. The goal of this field is for the reviewer to tag them once they are done reviewing:

I'm trying to create a new automation rule that will notify us when this field has at least 2 people. However, I'm a bit stuck with the JQL... I don't know how to "count" this field.
The only possibility I have so far is knowing that the reviewer field is empty or not.
Ideally, I would like to have a JQL like this one:
status = review AND Reviewers.count >= 2
I can't find anything about counting a field.... I'm a bit stuck here... Any help would be appreciated
