How is this click chat useful to me? you can open contact on the official WhatsApp app (or Business) with another user if you know their number to send a WhatsApp message to that person this was what this click to chat app does. This app replaces the method of saving the number into contacts 😀. This is like as clicking an unknown number on a group on WhatsApp, messaging him without saving his contact.
