@temnikovd To add the example to the the AWS Code Libary (and the Bedrock Runtime Service Guide), can you please:

1. add snippet tags (see below) around the code you want to display in https://github.com/temnikovd/aws-doc-sdk-examples/blob/nova_reel_java_example/javav2/usecases/video_generation_bedrock_nova_reel/src/main/java/com/example/novareel/VideoGenerationService.java
   I recommend:

• // snippet-start:[bedrock-runtime.java2.NovaReel.VideoGeneration] on line 6 and
• // snippet-end:[bedrock-runtime.java2.NovaReel.VideoGeneration] on line 100 of
