How could I render my rsx! to an html string?

[Plebshot]

I would like to print out the html that would be generated by my rsx! element. So far I've found this render_template_to_html function, but it only seems to work with static html, not dynamic components:

// Custom button component wrapper around DaisyUI's button classes
//
// The resulting html would be something like
// `<button class="btn btn-primary" data-dioxus-id="105">Primary</button>`
let preview = rsx! {
    Button { color: ButtonColor::Primary, "Primary" }
};

// This just results in
// `<!--placeholder-->`
let html = dioxus_elements::render_template_to_html(&preview.as_ref().unwrap().template);

I'm suspecting I need to actually render the item to an element or something. Any ideas?
