 The Mattermost Zoom integration allows team members to initiate a Zoom meeting with a single click. All participants in a channel can easily join the Zoom meeting and the shared link is updated when the meeting is over.
 
 **Important**: Only Zoom users associated with the Zoom Account that created the Zoom App will be able to use the plugin. You can add these users from the **Manage Users** section in the Zoom Account settings.
