I know you can do something like this:
const channel = await client.channels.fetch("Channel id");
channel.send('Message');
But what if I wanted to react to the message I sent? You need the message object to react right?
The TextChannel#send returns a Promise<Message>.
You'll have to await the message to be sent to be able to react to it.
const channel = await client.channels.fetch('Channel id');
const message = await channel.send('Message');
await message.react('๐');
console.log('Reacted to message.');
