-   Send Slack notification with instance details and request approval
-   Create SSM document after approval to automate resizing
-   Stop instance, modify instance type, and restart
-   Send progress updates to Slack during resizing
-   Wait for completion and send status
-   Clean up SSM document and send final confirmation
