Create a new Lambda function
This procedure guides you through creating the new Lambda function that will monitor the S3 bucket for changes.
Create a new AWS Lambda function in the same zone in which the S3 bucket resides.

Click Save.
Now, select the new function to view its details. In the Execution role area, click View the <function-name> role to edit the role permissions.
