The Host / Co-host / Moderator of the meeting can follow the guideline properly.
1. Disable “Join Before Host” so people can’t cause trouble before you arrive.
2. Enabling “Co-Host” so you can assign others to help moderate.
3. Disable “File Transfer” so there’s no digital virus sharing.
4. Disable “Allow Removed Participants to Rejoin” so booted attendees can’t slip back in.
