Implement a Lambda@Edge function invoked on viewer request, with execution role permissions for AWS STS, and move SDK calls to this function.
B
Use a CloudFront function invoked on viewer request, with execution role permissions for AWS STS, and move SDK calls to this function.
C
Deploy a Lambda@Edge function invoked on viewer request, incorporating credentials from the JSON file, and move SDK calls to this function.
D
Integrate a CloudFront function invoked on viewer request, incorporating credentials from the JSON file, and move SDK calls to this function.
