As @Guncixx already suggested, the best place to start is probably the integrations docs:
The docs team recently updated and improved this page, so if you have visited it in the past, this is a perfect moment to reread it.
The doc describes all your authentication options, like using the access key directly, IAM roles, and others. To learn more, check out the AWS Credentials section.
The most up-to-date list of permissions required is available in the AWS Permissions section.
