  console.log(`${changer} changed the group icon`);
  
  if (message.attachments && message.attachments.length > 0) {
    console.log(`New icon: ${message.attachments[0].guid}`);
  }

  console.log(`${remover} removed the group icon`);
});

await client.connect();

​
Event Methods

​
on()

Register a listener that will be called every time the event is emitted. 
client.on('group-name-change', (message) => {
  console.log(message);
});

​
once()

Register a listener that will be called only once, then automatically removed. 
client.once('participant-added', (message) => {
  console.log('First participant addition:', message);
});

​
off()

Remove a specific listener from an event. 
const handler = (message) => {
  console.log(message);
};

client.on('participant-removed', handler);

// Later, remove the listener
client.off('participant-removed', handler);
You must pass the exact same function reference to off() that was passed to on(). Anonymous functions cannot be removed.
