SendContactMessage.md

Sending a contact or contact list to a new or existing chat.

Implementation notes
The message will be added to the queue for sending and delivered even if the phone is disconnected from the Internet or authorization is not passed.
Only one of two parameters is needed to determine the destination - chatId or phone.
This method is available in both synchronous and asynchronous implementations
