Why we need to decode json web token ?

Hey guys I didn't get onething here in this code that why we need to decode web token in isAuthenticated function.

<?php
function decodeJWT($prop = null){
   \Firebase\JWT\JWT::$leeway=1;
    $jwt = \Firebase\JWT\JWT::decode(
            request()->cookies->get('access_token'), 
             getenv('SECRET_KEY'),
            ['HS256']);

    if($prop == null){
      return $jwt;
    }
   return $jwt->{$prop};
}

function isAuthenticated(){
    if(!request()->cookies->has('access_token')){
        return false;
    }

    try{
      decodeJWT();
      return true;
    }catch(\Exception $e){
      return false;
    }
}
?>
