Office 365 ATP Tools Audit Log

Hi Community,

I couldn't find any activity been logged for using ATP tools such as Explorer. I tried to move couple of users emails to Deleted Item (Threat Management - Explorer - View Malware - Email - Actions - Email Message - Move to deleted item) 2 days ago, but nothing has been returned in Audit log search yet. Just wonder whether this kind of admin activity in ATP tools are audited? Many thanks.

Regards,
