Practice Transcription Before Zoom Interviews

Hello, I am working on a doctoral paper and I am including interviews for my research.

I will need the transcription of the interviews to analyze after the interviews. I was going to use otter.io to transcribe during the interviews but I thought I'd see if Zoom offered full transcripts. I saw that I can record to the clould and I turned that on in my account but I wanted to practice with myself recording before I took it live with my interviewees. 

1) Can I schedule a Zoom call and practice on my own before my interviews? I want to see what the transcription looks like.

2) Where do the recordings go and where do I retrieve them from the cloud?

I have the Zoom One Pro version and live support is not available for me.

Thank you!
