Blueprint a Video Call App Inside Unreal Engine

In this tutorial, a video calling app is created using Unreal Engine with the Agora SDK plug-in. The process involves creating a basic C++ Unreal Engine project, installing the Agora plugin, creating game mode and implementing its life cycle, and finally implementing Agora callbacks and button functionalities in the UI. The resulting demo allows users to join video calls, mute their audio or video, and return to the introduction screen while maintaining the call session.
