This template creates an Alexa skill resource configuration. It retrieves the skill package from an S3 bucket and provides credentials for authentication with the Alexa service through Login with Amazon (LWA). The skill package is specified with the S3 bucket and key. The S3 bucket IAM role is specified along with the existing Lambda function. The manifest is overridden to specify the custom API endpoint URI. The authentication configuration includes the client ID, client secret, and refresh token. The vendor ID is also provided.
