How to get messages from selected topic

[Cong Luong Van]

Here is code. But console.log nothing

function selectTopic = (topic) => {
       const t = tinode.getTopic(topic.name)

    if (!t.isSubscribed()) {
        let getQuery = t.startMetaQuery().withLaterDesc().withLaterSub().withLaterData(25)
        t.subscribe(getQuery.build())
            .then(() => handleMessages(topic.name))
    }
}

function handleMessages(topicId) => {
    const topic = tinode.getTopic(topicId)
    topic.messages((message) => {
        console.log('loop message', message)
    })
}

This promise gets resolved on subscription confirmation, before the messages are received. See here:
