WinUI3, WASDK: Cannot add Input.Toggle into CarouselPage

I try creating Windows 11 widgets. But have problems with writing templates. I need Carousel with checkboxes, it should looks like this:

"type": "Carousel",
"height": "stretch",
"rtl": false,
"pages": [
{
    "type": "CarouselPage",
    "id": "firstPage",
    "items": [
             {
                 "type": "Input.Toggle",
                 "title": "Title 1",
             }],
             "rtl": false
             },
             {
     "type": "CarouselPage",
     "id": "secondPage",
     "items": [
              {
                  "type": "Input.Toggle",
                  "title": "Title 2",
               }],
               "rtl": false
}
]

But I get error: [Parse] Element type "Input.Toggle" is not allowed in this context. I cannot found any useful docs for widgets, there is no Carousel control in Schema Explorer. I don`t have any ideas.

I am try use Input.Toggle inside Container - it did not help.
