Return shadow-AI usage rolled up per AI tool and per member from the on-device AI-prompt security events, for a member (user) or across one or more groups (groups), else the whole organization. Each tool reports how many PII-bearing prompts were seen, how many were intervened (block/softBlock/redact), and how many distinct members used it; each member reports the same counts and the tools they used. Tools are attributed at report time from the shipped AI-tool catalog. Restricted to organization admins/managers and gated by the activity-tracking flag.
