To enable users to share or add contacts directly from their Google Contacts dashboard, and to minimize wasted time spent on swapping between applications, we recommend utilizing the ContactsFlow™ (formerly Shared Contacts for Gmail™) Chrome Extension.
This plug-in allows our users to occupy a friendly, centralized space of contact sharing within their already inhabited Google Workspace, maximizing team efficiency. The users benefit from having sharing abilities added to their Google Contacts interface, as it gives them the ability to share contacts exactly like you share Google Drive folders and documents.
This plug-in does not require any third-party apps. ContactsFlow™ (formerly Shared Contacts for Gmail™) is fully integrated into Google Contacts Manager.
