Make a beep sound when a message containing a string is sent in a channel

My main purpose was looking for a message that contains (...) and make a beep sound

• Beep when a msg include a string
• Remember already seen messages to not re-beep
• Add a reaction to found messages
• Check last 100 messages every 15s

function beep() {
    const context = new AudioContext();
    const oscillator = context.createOscillator();
    oscillator.type = "sine";
    oscillator.frequency.value = 800;
    oscillator.connect(context.destination);
    oscillator.start();
    setTimeout(() => oscillator.stop(), 1200);
}

{
    id()
    const search = 'mange'
    const channelId = cid

    const seenMessagesIds = new Set()
    var loop = true
    while (loop) {
        const messages = await api.getMessages(cid, 100)
        const found = messages.filter(msg => msg.content.includes(search) && !seenMessagesIds.has(msg.id))
        if (found.length > 0) {
            beep()
            for (const msg of found) {
                console.log(`Found message ID=${msg.id} "${msg.content}" by ${msg.author.username}#${msg.author.discriminator} ID=${msg.author.id}`)
                seenMessagesIds.add(msg.id)
                await api.addReaction(msg.channel_id, msg.id, '🤔')
            }
        }
        await api.delay(15000) // wait 15s
    }
}
