Data extraction from registrations on webinars

[Geoplat]

Hi,

I do host webinars using Zoom and would like to know how can I extract data from registrations to the webinars? In registration form there are fields like Company, Country, Position which are not present in CSV reports. How can I access these fields and extract data from them?

Done anyone answer on here?
