Teams User Activity reports or APIs

Are there existing reports or APIs that end users can use to see their teams activities?  Our users would like to see reports of things like when they started and stopped meetings, Teams calls, and PSTN calls.  They'd use this information to help fill out timesheets.  I've seen admin level reports that show totals, but not start/end times.  I can also drill into specific calls/meetings, but that's a manual process for each user/call/meeting.  Thanks.
