How do I activate this discord Js?

Everytime I type node . into the terminal, It says im missing an emmiter from a messageCreate from this area and im not sure if i made a typo or anything, but help would be appreciated.

const client = new Client({ 
        intents: [GatewayIntentBits.Guilds,
                  GatewayIntentBits.GuildMessages, 
                  GatewayIntentBits.MessageContent 
                 ] });
