Automation - Sending a mail to the people of a Jira Team

Hi,

I would like to use the automation rules to inform people of a Jira-Team when a task related to the Team is closed. The problem now is, that I can't assign the Team to the email receiver list. The only options there are groups and fields from the task. Groups could be used, but in this case I don't have the rights to edit groups and our admin doesn't want to maintain extra groups just for this purpose.

So the possibility to send automated mails to the people of a Team would be very helpful.

Thanks!
