Feature description
This issue tracks the addition of an AWS Lambda Responder to integrate with TheHive. The new responder will allow users to invoke an AWS Lambda function directly from TheHive using Cortex, for automated response actions.

Describe the solution you'd like

• Supports both RequestResponse and Event invocation modes.
• Allows users to specify the AWS Lambda function name, region, and credentials.
• Handles successful and failed invocations with detailed messages.
