Need to record 1 Co-Host Speaking and Screen Sharing, while recording video feed of 2nd co-host

I am running a live seminar and broadcasting it on Zoom- Friday was day one, TODAY is day 2- I recorded with Fathom and it only recorded the Audio and the Presentation of the co-host sharing, and it did not record the other co-host whose video was pinned.

I have Workplace Pro- and I just upgraded my Cloud storage to 30 GB

Will this work if I record to the Cloud Storage?

And will approx 10 hr event fill 20 GB?

Do I have to buy a $79 Webinar?

please help- event starts in 6 hours.

Thank you- I'm clearly not Next Level in my Zoom game lol
