I'm using KaafkaJS to connect and consume the kafka messsages. I'm using the following code to consume messages. But it fetches all the messages but I would like to store the last message in the variable messageValue. Can someone help me with it please.

await consumer.run({ 
            eachMessage: async (data) => {
                    messageValue = data.message.value.toString('utf8').trim()
            }
        })
console.log(messageValue)
