I'm trying to make a script to read all the messages from a Google Group and count how many from specific label there are. I have a collaborative inbox to manage issues and I would like to build reports with this information.
I have checked Group and GroupsApp classes, and they don't allow to access messages, they only give you global information from the group (email, users, roles...).
I tried to use GmailApp, but I can only retrieve my own messages (I usually delete group messages from my inbox).
Could be possible to access the group messages?
Thanks
