Issue Summary

Currently, the JQL function "membersOf" is valid only when used with the user groups. It should be possible to search for the users belonging to a "Team" (People section) using this function. 

This would be useful while configuring automation that searches for users who are part of a Team. 

Workaround

The workaround for this would be to create a Group with the same members of the Team and add that Group in the JQL while configuring the Automation.
