-- You can remove individual permissions from an access policy associated
-- with a Lambda function by providing a Statement ID.
--
-- Note that removal of a permission will cause an active event source to
-- lose permission to the function.
--
-- You need permission for the 'lambda:RemovePermission' action.

-- \"arn:aws:lambda:us-west-2:account-id:function:ThumbNail\"). AWS Lambda
-- also allows you to specify only the account ID qualifier (for example,
-- \"account-id:Thumbnail\"). Note that the length constraint applies only
-- to the ARN. If you specify only the function name, it is limited to 64
-- character in length.
