	const GET    = { headers: { Authorization }, method: 'GET'   };
	const DELETE = { headers: { Authorization }, method: 'DELETE'};

	const sleep = ms => new Promise(resolve => setTimeout(resolve, ms));

	const me = await fetch('/api/v6/users/@me', GET)

		for (let i = 0; i < ids.length; i++) {
			console.log('Deleting message', ids[i]);

			const r = await fetch(`${url}/messages/${ids[i]}`, DELETE);
