How to get group name from user

[Gianni Minicozzi]

Hi all,

I cannot find a way to get the group name in which a user is a member (the user is declared into a user picked field) from Automation for Jira, I need this information to set the issue security scheme automatically.

For example: if the user "John" is declared into the user picker field and John is a member of the group "Developers", I want to set the issue security scheme based on the group "Developers" automatically.

How can I get this info? 

Thank you,

Gianni
