Trigger Glue Crawler with S3 bucket event

Hello.

Since the S3 event trigger cannot directly trigger the Glue crawler, you need to create a configuration using SNS or SQS as per the documentation you checked.
https://docs.aws.amazon.com/AmazonS3/latest/userguide/EventNotifications.html

I think it is also possible to run the Glue crawler using Glue workflow and EventBridge event using methods other than S3 event triggers.
When using EventBridge event, there is no need to create SNS or SQS.
