is it possible to add mail merge features in google groups automatically?

I personally don't know however I did find some documentation about Mail Merge, which are located at https://workspace.google.com/marketplace/app/group_merge_mail_merge_for_gmail/586770229603 and https://developers.google.com/workspace/solutions/mail-merge. I assume if you can email the Google Group or that label in Gmail, that mail merge might have a chance of working but I don't know how or if it's automatic. 
Did you know there is an entire Google Group dedicated to the Mail Merge for Docs/Sheets at https://groups.google.com/g/mail-merge-documents?pli=1 ? It does look like the moderators for that group are active.
