Fetch user from different shard (without being in the same guild)

            // Pick random shard to dm user to prevent dulicate message
            const totalShard = manager.totalShards;
            const rngShard = getRandomInt(totalShard);
            manager.broadcast({ name: 'dmUser', id: id, msg: msg, shard: rngShard });

process.on('message', async function(m) {
        //...
    if (m.name === 'dmUser') {
        // Check if this shard is the one assigned to dm user
        if (client.shard.ids[0] === Number(m.shard)) {
            const user = await client.users.fetch(m.id);
            if (!m.msg || m.msg === '') {
                return;
            }
            await user.send(m.msg);
        }
    }
