Amplified Labs uses Google's APIs to gather information about your Google Resources. If your domain has restrictions on API scopes, you'll need to manually trust the Addon or application. This is done in Security -> API controls-> Manage Third-Party App Access in the Admin console. Here you will see a list of Apps that have been already added, the services they request, and their level of access. Select OAuth App Name or Client ID from the Configure new app drop-down and search for the tool you're installing. You'll repeat this process for each Addon or App you need to trust.
