What is the format of the CVS file for importing email groups?

I can't find a sample CSV file for importing the email groups like it was provided for importing users and importing accounts.
I expected to see a download link for the help page:https://www.zoho.com/mail/help/adminconsole/creating-groups.html#alink4

Could someone provide me with a sample csv file or an image?
