Chat upsert does not provide sent/received message data

[rahmat-why]

I've done console.log but the sent/received message data doesn't appear

Code:

socket.ev.on('chats.upsert', (data) => {
    console.log(JSON.stringify(["UPSERT", data]))
})

Response: ["UPSERT",[{"id":"628xx@s.whatsapp.net","conversationTimestamp":167xxx,"unreadCount":1}]]

It's the default behavior of baileys event emitter and i couldn't do anything about it
