How does one audit the change history of a Google Group?

[ZaneP]

I have an integration between a Google Group that receives emails and forwards them to Slack.  Somehow this Slack email address was removed from the Google Group.  How can I investigate how this user was removed?  This email address is a key function of our organization, and I want to make sure whatever happened to break it does not happen again.  I appreciate any direction.

Maybe you could find some record of the change in the log event data, as described at https://support.google.com/a/answer/11339435 ? If you do, you can create reporting rules there to alert you of any changes you might consider problematic.
