I've just about completed the Team Inbox for WhatsApp so that you can see all messages inside a single inbox in Teams or on the web. So with this integration you you can chat with your WhatsApp customers from Slack, Teams, or Google Chat. So you just set up your business account number and integration with Social Intents for one team inbox view all of your team members can manage just like website chats.
