Take Attendance During Meeting

Meetings hosted by paid accounts will automatically create an attendance report, which is available to the host after the meeting. You can find out more about reporting here: https://support.zoom.us/hc/en-us/articles/201363213-Getting-started-with-Zoom-reporting

If you are not a licensed user, you would not have attendee reports for your meeting, so you would need to take attendance another way, such as taking a screenshot of the participants list. 

Hope that helps and please make sure to mark the solution as accepted if this information is what you needed.
