Seeking a WhatsApp Business App (not API) Zoho CRM integration

Seeking a WhatsApp Business App (not API) Zoho CRM integration

We have a business need to integrated WhatsApp Business App (not API) into Zoho CRM to centrally manage communications between our Sales team and Leads & Contact. 

Is there a reputable integration available for this scenario of ours?

Core features we would like:
  1. Send & Receive all whatsapp communications (messages/media/documents) within a Lead/Contact within thier crm record by automatically matching the phone number.
  2. Retain a historical record or all communications (messages/media/documents) sent/received to a Contact/Lead within Zoho.
  3. Be able to log unknown whatsapp messages received as new Leads

Any guidance on a solution to this will be greatly welcomed.

Thank you.
