видеовызов twilio JS/.Net MVC

Я реализую функцию видеозвонка twilio, используя Javascript и MVC .net. Когда я запускаю проект, веб-браузер запрашивает разрешения для камеры и микрофона, но не показывает камеру.

Я не могу найти ничего связанного с документацией. https://media.twiliocdn.com/sdk/js/video/releases/1.14.0/docs/index.html

Если кто-то может определить ошибку здесь, это было бы здорово. Спасибо
