Request for Mixpanel Audit Data After Unauthorized Access Incident

Hi Folk, I have a client that's worried because an ex-employee accessed their Mixpanel account. I deleted the user, but now I can't see their data in the Usage>Active Users dashboard. I've been further asked to find out when in the last 90-days the employee logged in, and what data they downloaded. There doesn't seem to be a way to do this via the UI. Is there someone at Mixpanel who would be able to pull this audit data for me?
