### Description

Hi,

The `AWS::SecurityHub::AutomationRule` CloudFormation resource `Criteria` property `AutomationRulesFindingFilters` [1] doesn't currently support `AwsAccountName`.

This is supported by Security Hub [2].

Please review and address this coverage item - thanks.

### Other Details

_No response_

Start with the AWS::SecurityHub::AutomationRule resource and its Criteria.AutomationRulesFindingFilters property, then compare the linked CloudFormation and Security Hub references. Done means AwsAccountName is accepted for this property with the listed string-filter operators and the resource coverage reflects the addition.
