Chrome app and extension permissions

For administrators who manage Chrome browser or ChromeOS devices for a business or school.

As a Chrome Enterprise admin, you can control whether your Chrome users can install apps or extensions based on the information an app can access—also known as permissions. For example, you might want to prevent users from installing apps that want permission to see a device location.
