Allow deletion of scheduled items from web app

• [ ] (add issue for later) Should this be done with Amplify? Lambda? What is the correct way to do this?

[alyoshenka]

amplify import storage

Doing with Lambda for now because I understand how it works.

[alyoshenka]

npm install @aws-sdk/client-dynamodb
