How to request phone numbers in viber api?

Question

Python

In viber it is possible to make a button with sending a contact

{
  ...    
  "ActionType": "share-phone",
  "ActionBody": "reply",
  "Text": "Зарегистрироваться"
},

The documentation says that if "ActionType": "share-phone" then "ActionBody" should
be
none on the mobile client,
but on the desktop it doesn’t work, text arrives: reply
If someone has already done this functionality, throw off the json that you send

Answer 1

For those who periodically get here on the same issue
1. Viber support replied that this functionality is not available in the desktop client
2. For mobile clients, you need to specify min_api_version 3 or higher to make it work

Answer 2

differs from the regular menu by 3 lines
+1 in the menu $data['min_api_version'] = 3;
and replace two in a specific button
$getphone['ActionType']="share-phone";
$getphone['ActionBody']="phone";
