Supported Rich Results types

Hi,

Am I right to assume that only types listed in the search gallery are
supported by the Rich Results test tool?
https://developers.google.com/search/docs/guides/search-gallery
https://search.google.com/test/rich-results

If I put the following snippet into the test tool, it says "Page is
eligible for rich results".
However if I change the @type to http://schema.org/WebPage, I get
"Page not eligible for rich results known by this test".

Is this documented somewhere?

<script type="application/ld+json">
[{
"@context": {
"j.0": "http://schema.org/",
"title": {
"@id": "j.0:name"
}
},
"@id": "https://localhost:4443/",
    "@type": "http://schema.org/Article",
"title": "Root"
}]
</script>
