There is no option available to integrate Sell contacts with Google

Issue symptoms

There is no option available to integrate Sell contacts with Google.

Resolution steps

If the Google integration is not available under Settings > Integrations, the permission Can add contacts was disabled when editing user role permissions. The Google sync is removed from the integration when the permission was removed from the user. 

For more information on how to update those permissions, see the article: Editing user access permissions in Sell.
