'401 when fetching Discord channel messages using RestCord

I'm using Restcord ( Restcord.com ) to connect to Discord. I'm using OAuth instead of Bot

use RestCord\DiscordClient;
$token = $_SESSION['access_token'];
$discord = new DiscordClient(['token' => '$token','tokenType' => 'OAuth']); 
var_dump($discord->channel->getChannelMessages(['channel.id' => 924525404658749500]));

Yet I'm getting a 401 Unauthorised.. Its not private and the OAuth token creation was successful so I'm puzzled
