send email to Group (as defined under USer Management, not as a form in a creator application)

send email to Group (as defined under USer Management, not as a form in a creator application)

what is the script for referring to a Group if I want to send an email to that group on a field-update action.
the group is not a list of emails in a table in the application.  The Group is defined under "User Management"

I know zoho.adminuserid refers to "me".

but if the group name is "Cost_Change". then what is the deluge script to find this?

thanks
