New; can't find history of meetings I have joined

I have been joining someone's meetings for training. I am now trying to backtrack and seeing how many hours of zoom time I have spent with this person for my time spent training.  I cannot figure out how to find my history.  I logged in and looked under "Meetings/Previous" but it shows nothing, which is far from the truth.  These are meetings they set up and I joined in.  Is there any way I can find the dates/times I joined these meetings?
