Security Log should cover features in "Folder Settings".
Specifically, the setting called "Only folder owners and co-owners can send collaborator invites".

We don’t currently plan to add this to the logs.
However, it should be noted that there are compensating controls for this, such as restricting the ability to change this setting at the EID level, or not adding users as Editors in folders where there is sensitive material.
