CloudFormation IaC generator cannot find any Cognito resources

There are a few potential reasons why the CloudFormation Infrastructure as Code (IaC) generator scan may not be finding any Cognito resources:

1. Limited support: The IaC generator has limited support for Cognito resources. According to the resource type support information, only a few Cognito resource types are supported by the IaC generator. Specifically, only AWS::Cognito::IdentityPoolPrincipalTag is listed as supported for IaC generation. Other common Cognito resources like UserPools, IdentityPools, and UserPoolClients are not supported by the IaC generator.

2. Regional availability: The IaC generator only supports resources that are also supported by the Cloud Control API in your specific AWS region. It's possible that Cognito resources may not be supported by Cloud Control API in the region you're scanning, which would prevent the IaC generator from detecting them.

3. Resource configuration: If your Cognito resources were not originally created or managed through CloudFormation, they might not be detectable by the IaC generator scan.

To work around this limitation, you may need to manually create CloudFormation templates for your Cognito resources or use alternative IaC tools that have better support for Cognito resources. Additionally, you could check if your Cognito resources are supported by Cloud Control API in your region, as this is a prerequisite for IaC generator support.
