Research direction

Start by inspecting the SAM template containing ActivitiesTable, its Table parameter, and ListActivitiesFunctionRole, then reproduce with sam build and sam deploy --guided using a nondefault table name. Done means the deployed function can scan that table and the endpoint shows an empty screen instead of an Access denied exception.
