Zoom Apps External User

How can I turn off the ability for external users to use third-party apps from the Zoom Marketplace?

An organization-internal user is claiming that an external user has been using a third-party app in meetings hosted by one of our internal users. For internal users, any and all apps must be approved by an admin, but I cannot find a setting that limits the permission of outside members. If this is not possible, it would be a security-friendly feature for organizations to control the apps that interact with our meetings.

More info: This specifically is referring to Read.AI Meeting Notes. We require all apps to approved by an admin, but an external user was still able to use it and it joined our organization-hosted meeting.

Update: I believe that the Read.AI is able to circumvent blocked domains, as it appears as a guest in the Zoom records.
