How to define a Cost Category with additional logical operators such as NOT and OR besides AND

The General AWS Cost Categories FAQs and documentation mention that using the JSON Editor in the Cost Category creation Console, one can

define a Cost Category with additional logical operators such as NOT and OR besides AND

But I can not find any example and my attempts all lead to errors being flagged in the JSON editor. Would love to find some examples of how to specify the OR of several Tags.

The CostCategoryRule says Root level OR isn't supported. We recommend that you create a separate rule instead. But I have no idea how one could create a separate rule that would do what I need.

What I would like to do is the following, but it currently gives me the error Failed to create Cost Category: Expression cannot contain OR on root level:

{
	"RuleVersion": "CostCategoryExpression.v1",
	"Rules": [
		{
			"Type": "REGULAR",
			"Value": "production-001",
			"Rule": {
				"Or": [
					{
						"Tags": {
							"Key": "Environnment",
							"Values": [
								"prod"
							],
							"MatchOptions": [
								"EQUALS"
							]
						}
					},
					{
						"Tags": {
							"Key": "Environment",
							"Values": [
								"prod"
							],
							"MatchOptions": [
								"EQUALS"
							]
						}
					},
					{
						"Tags": {
							"Key": "TerraformWorkspace",
							"Values": [
								"prod"
							],
							"MatchOptions": [
								"CONTAINS"
							]
						}
					},
					{
						"Tags": {
							"Key": "aws:ecs:clusterName",
							"Values": [
								"prod"
							],
							"MatchOptions": [
								"CONTAINS"
							]
						}
					}
				]
			}
		}
	]
}
