Hello,
My name is Brandon. Thanks for joining the Zoom Community! Security settings are set to the hosting account. If you were to promote a co-host to the level of the host, the security settings would still pull from the original host of the account. Co-hosts' account settings only apply to meetings that they host personally. Now, that said, if the co-host account admins do not allow the user to chat in a Zoom Meeting, then the user, whether a co-host or a participant, would not be allowed to chat "in meeting" no matter what the host's security settings are enabled on the account. Your security settings follow you personally as you traverse between meetings. Still, the meeting security settings are primary in any meeting that the user hosts.
