We are using Google Workspace Enterprise Standard plan for our company emails. Recently we found out that in some of our groups the "conversation history" setting was set to "on" and the "who can view conversations" setting was set to "entire organization" which caused all the conversations to be archived in the group and non-members of the group (but members of the organization) to be able to view these conversations.
Google creates group pages in the form of https://groups.google.com/a/**companydomain.com**/g/**groupname** So if any member of the organization visits this page (intentionally or accidentally) he/she can view all the conversations.
Having noticed that, we turned off the necessary access settings but we want to audit who accessed these conversations during a certain period.
We tried "investigation tool" under "security center" with using "groups enterprise log events" and "groups log events" as data sources but had no success. These data sources only provide "group creations" and "member additions to/removals from groups".
Any idea how to view the access logs for the https://groups.google.com/a/companydomain.com/g/groupname page and the conversations in it? Or is it even possible?
Thanks in advance.
