Twilio's taskrouter.js is throwing a CORS policy error when I call the worker.completeTask or reservation.task.complete()

Question

I am attempting to move the Taskrouter task from "wrapping" to "completed" programmatically when the agent is done with their post-call duties. Other method calls to worker or reservation work, but when trying to call either worker.completeTask or reservation.task.completed, I receive a CORS policy error "No 'Access-Control-Allow-Origin" header present. Since taskrouter.js is an external Twilio script and I can't change it, is there any way to get this to work?

After spending hours scouring the Twilio docs earlier today, I finally posted this question in frustration. Then, literally, 30 minutes after posting it, I was working on something else and came across the solution.

When generating my capability token, I was doing it as their tutorial suggested:

$workerCapability = new Twilio\Jwt\TaskRouter\WorkerCapability(
    $accountSid, $authToken, $workspaceSid, $workerSid);
$workerCapability->allowActivityUpdates();
$workerToken = $workerCapability->generateToken();

The stumble led me to an additional capability, so the updated code is:

$workerCapability = new Twilio\Jwt\TaskRouter\WorkerCapability(
    $accountSid, $authToken, $workspaceSid, $workerSid);
$workerCapability->allowActivityUpdates();
$workerCapability->allowReservationUpdates();
$workerToken = $workerCapability->generateToken();
