Compliance and Audit Reporting

I am looking for a way to report on Secrets and Password access in a SIEM, like Microsoft Sentinel. I need to report the user, the collection, what they did (view, update), and when. I need to be able to break that down by collection and user. However, I’m not seeing anything in the SIEM schema for Secrets. Please know I’m familiar with all the existing reports in BW, and none of them fit the bill.
