Has anyone tried using tools for business communication over WhatsApp?

Imagine if you had something like Intercom or better for managing WhatsApp Business. I recently came across Rasayel, a business communication platform that helps businesses close more deals and reduce support time in half by offering robust automations, chatbot builder, shared team inbox, mass broadcasts, and analytics features. I use it for use cases related to sales, customer service and customer engagement over WhatsApp. They launched on Product Hunt today so I wanted to give them a shoutout: https://www.producthunt.com/posts/rasayel Have you tried any tools for business communication over WhatsApp?
