You can read the attachments inside a message at the key attachments

See in the Discord documentation, the Message data model

Example image attachment

{
    "id": "1198292395519909948",
    "filename": "2024-01-07_23-28-19.png",
    "size": 10358,
    "url": "https://cdn.discordapp.com/attachments/826934811846377545/1198292395519909948/2024-01-07_23-28-19.png?ex=65be5fc2&is=65abeac2&hm=b4a6d3c271e28969e5ae836c776f3597ceda7b326c24949f30b43a29a7791cde&",
    "proxy_url": "https://media.discordapp.net/attachments/826934811846377545/1198292395519909948/2024-01-07_23-28-19.png?ex=65be5fc2&is=65abeac2&hm=b4a6d3c271e28969e5ae836c776f3597ceda7b326c24949f30b43a29a7791cde&",
    "width": 144,
    "height": 127,
    "content_type": "image/png",
    "placeholder": "x/cBBoAnqGaGeIeAeaNXmEeEqXyPXvU=",
    "placeholder_version": 1
}

You can then use this function to download the attachment. I liked the idea, so I added it directly in the API 5a5063a

Final code

;(async () => {
    api.update_guildId_and_channelId_withCurrentlyVisible()
    let channelId = api.getConfig().channelId

    const messages = await api.getMessages(channelId)
    console.log(messages)
    
    console.log('List of attachments in the latest message', messages[0].attachments)
    console.log('URL of the first attachment in the latest message', messages[0].attachments[0].url)
    api.downloadFileByUrl(messages[0].attachments[0].url, messages[0].attachments[0].filename)
})()
