## Example

```ts
// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import { aws_quicksight as quicksight } from 'aws-cdk-lib';
const cfnCustomizationProps: quicksight.CfnCustomizationProps = {
  defaultTheme: 'defaultTheme',
  namespace: 'namespace',

  // the properties below are optional
  tags: [{
    key: 'key',
    value: 'value',
  }],
};
```

## Properties

- `defaultTheme`: string (required) — The ARN of the theme applied by default in the QuickSight console for this namespace.

  May be an AWS-managed starter theme such as arn:{Partition}:quicksight::aws:theme/MIDNIGHT or a theme owned by this account.

- `namespace`: string (required) — The QuickSight namespace the customization applies to.

  One customization exists per (account, region, namespace), so this is create-only: changing it addresses a different resource.

- `tags`: [CfnTag](/cdk/api/v2/docs/aws-cdk-lib.CfnTag.html)[] — Tags applied to the customization.

  QuickSight rejects any key prefixed aws: or quicksight:, so CloudFormation system tags are not propagated.
