API Call - Help with "Add Cache Refresh Plan"

I'm not sure why they moved away from using SwaggerHub for documentation, but the docs there still have an example of how to call this api https://app.swaggerhub.com/apis/microsoft-rs/PBIRS/2.0#/CacheRefreshPlans/AddCacheRefreshPlan And when I use the browser tools in Edge it captures the POST call to create a cache refresh plan.

Below is an example I captured when creating a scheduled refresh for my Power BI report called "local Adv Works"

{
	"Owner": null,
	"Description": "test2",
	"CatalogItemPath": "/local Adv Wrks",
	"EventType": "DataModelRefresh",
	"Schedule": {
		"ScheduleID": null,
		"Definition": {
			"StartDateTime": "2025-07-01T04:00:00+10:00",
			"EndDateSpecified": false,
			"EndDate": "1901-02-01T00:00:00+10:00",
			"Recurrence": {
				"DailyRecurrence": {
					"DaysInterval": 1
				}
			}
		}
	},
	"ScheduleDescription": "",
	"ParameterValues": []
}
