Optionally configure log retention

During this phase of setup, you can customize the log retention policy for Amazon S3 buckets that store your AWS CloudTrail logs in AWS Control Tower, in increments of days or years, up to a maximum of 15 years. If you choose not to customize your log retention, the default settings are one year for standard account logging and 10 years for access logging. This feature also is available when you update or reset your landing zone.
