How to obtain attendance report if I was just an attendee

Hello,

I attended a zoom meeting 10 months ago.  I still have the Zoom meeting ID number, password, date, and time the meeting occurred.  I was not the admin or host of the meeting.  I was just an attendee.  But now I really really need proof of who attended that meeting.  How do I obtain it? 

 I signed up for a zoom account today with the same email address that was used in that meeting 10 months ago.   I clicked on Reports but it prompts me to Upgrade.  If I upgrade, will I be able to see the attendance of this prior meeting if I was just an attendee?  Or will I still have to rely on the host of the meeting to obtain the list of attendants?

Also, how long after the meeting is held is the attendance report still available?  A month? A year? etc?
