unable to find recording to turn into mp4 for university

Good afternoon everyone,

I spent nearly all day yesterday recording various meetings yesterday for university.  I now cannot find them.  They are in template form but I cannot find the actual recording to playback or send to university as mp4.  I am panicking as it needs to be submitted by 1400 hours monday,

I have tried to call zoom but it said that they could not verify my account despite using host pin and meeting number.  I have also used that awful chatbot who was talking absolute nonsense telling me to access areas which I do not have as I only have the basic package.  All it keeps telling me is to upgrade and I refuse as I will not be using this again after today.  Any help will be appreciated
