terraform - how to add s3 Object Created trigger for lambda

How do I add a trigger to aws lambda using terraform? the desired trigger is s3, object created all.

my terraform source code arouond the lambda is:

module "s3-object-created-lambda" {
  source = "../../../../../modules/lambda"
  s3_bucket = "${var.s3_lambda_bucket}"
  s3_key = "${var.s3_lambda_key}"
  name = "${var.lambda_some_name}"
  handler = "code.handler"
  env = {
    lambda_name = "${var.lambda_base_name}"
    lambda_version = "${var.lambda_version}"
  }
}

trying to figure out how do I add the trigger. via the aws console it is super simple.
