Mark sent messages as received and messages read by the recipient!

Bonjour,
Serait il possible, comme avec WhatsApp par exemple, de marquer, pour un message envoyée, que le destinataire a bien reçu le message,
et quand le message a été lu par le destinataire faire également une marque !
Merci et bon courage 

Hello, Would it be possible, as with WhatsApp for example, to mark, for a message sent, that the recipient has received the message, and when the message has been read by the recipient also make a mark! Thank you and good luck
