Create a Cognito Pool Id and add it in your scene by pasting the Id in the `AWS Configuration` component in the Inspector panel.
This is important if you are using other AWS services like AWS IoT, Polly, Lex in the Sumerian scene.
You can create the Cognito Pool Id from the CloudFormation template.
You can add the host in the scene from the Import Assets option.
You can change the host's `Point of Interest` component to any entity to make it look more realistic. Generally, you would like to use the default camera as the `Drop Entity`.
Another host component is `Animate Using Speech`. Lip sync and gestures are self-explanatory. `Gesture Hold Time` is the number of seconds you want your host to hold the gesture (keep it 1 sec). `Min Gesture Period` is the wait time between two gestures (keep it 0.1 sec).
Amazon Polly is a text to speech service provided by AWS and you can integrate that service with your Sumerian host.
