Accessing exact # of minutes of previous meetings

[ZoomCommunity1]

I hired someone to help me with a project.  We met over zoom @ 5 times.  I now need to pay him for that time.  The time is also discrepant from what I originally scheduled (we usually ran over).  The meetings were unrecorded.

I'm pretty sure that zoom includes a feature where I can find the exact minutes actually zoomed per meeting.  Needging help in finding that information.

Thank you ~
