how to add a listener so if someone sent message in the server, the bot does action ?

client.on('ready', () => {
        console.log(`Logged in as ${client.user.tag}`);
      });

    client.on('message', (message) => {
        // Code to handle incoming messages
        console.log(`Received message: ${message.content}`);
      });

client.on('ready', () => {
        console.log(`Logged in as ${client.user.tag}`);
      });

    client.on('message', (message) => {
        // Code to handle incoming messages
        console.log(`Received message: ${message.content}`);
      });
