Hi @横田 大和 ,
The article you linked is about fetching from S3 to Sentinel and not the other way around. The Amazon Web Services S3 connector allows you to ingest AWS service logs to Sentinel, and it can ingest logs from various AWS sources. You need to use the connector to do this and the logs flow from AWS to Sentinel.
To query files from Microsoft Sentinel, you can use the Log Analytics agent. https://learn.microsoft.com/en-us/azure/sentinel/connect-custom-logs?tabs=DCG
You can use the Sentinel API with a Get request to query incidents, if this is what you were hoping to accomplish:
