Show HN: I made a tool to list your AWS account Lambda Function invocation time

I made a tool to list your AWS account Lambda Function last invocation time.

Currently, AWS doesn't provide Lambda Function's last invocation time on AWS console. You can only check it for individual Lambda Function by using its metrics or logs manually. This tool aims to help Cloud Administrator to perform account checkup and cleanup by providing a list of Lambda Functions last execution time in a CSV table.

This tool works by querying Lambda Function logs in the CloudWatch Log Group and check the latest log timestamp. I made it so that it queries multiple log groups concurrently for a faster execution time.

I'd love to listen to the feedback on the code, project architecture, and design pattern I made.
