Whenever steps such as group membership changes are performed in IT Shop, it is at the database level. That is, the Person record for the group manager makes changes at a database level for group membership as defined in the 1IM database.
Following the database changes, the 1IM service account will execute these changes in the target system, in this case ARS.
That's why group membership changes appear in ARS change history, and that the operation is initiated by the 1IM service account. This is the account connecting to the target system to make such changes.
Identity Manager has its own change history available that would allow you to track this type of change in the database.
