Retrieving a zoom classroom meeting

Hi there,  I was wondering if there was a way to retrieve the video from a classroom meeting even though I didn't record it on my end.  It's a pretty serious situation where some baseless accusations are being made, and I was hoping that the complete video might help me prove my case.  At the very least, is there someone I can contact to dig a little bit deeper into seeing if retrieval of this video is possible?  Thanks.
