Showing phone button on whatsap api

WhatsApp Api has released its newest feature, namely being able to make calls, I ask the botsailor management to add this feature, so that we can use it for our customer service well. This feature is very helpful in serving my customers. Thank You

Yes correct thanks for raising request. @botsailor please take a look on this essential feature; thanks

Would you please describe it in more details and can you share any links which feature you are referring to actually. Thanks
