Regarding the Savings plans / reservations expiration CloudWatch alerts, I've verified that it's not feasible to directly integrate them with Chatbot -> Slack. While the AWS Console now offers the ability to create these alerts, they are configured to send directly to email without an SNS topic. This functionality hasn't been introduced in the API yet.

A potential solution is to implement this via a Lambda function. For reservations, AWS already provides an example. For savings plans, one could simply describe and check the "end" attribute.
