Every attendee can upload a document, and share it with the other participants. As organizer you can share a pdf of the invitation mail, or a pdf of the agenda of your meeting. Or of the entire ppt that you would like to show. That way, you reserve the zoom or webex window to the faces of the attendees - and literally keep an eye on the interpersonal dynamics. Also, when others want to share a document, you can invite them to upload it directly to the report. The document will be uploaded with the original file name, but you can change that any time while writing your report. Or delete it, if it should not be part of the final report.
