Title. I couldn't find anything on this online or on stackoverflow.
What you could do is have a message event listener which collects all messages, and then use client.channels.cache.get("CHANNEL ID").send(message.content).
client.on("messageCreate", (message) => {
if(message.guild.id !== "GUILD ID MESSAGES ARE RECEIVED IN") return;
client.channels.cache.get("CHANNEL ID").send(message.content)
})
