How can I pass a JSX.Element as prop in Qwik?

Question

I have two components in Qwik V 1.2.6 the first one is the parent and looks like that:

.
.
.
return (
<Dropdown
   element={<h1>Hello world</h1>}
/>
);
.
.
.

the child component receives as prop the element JSX object

export default component$((props: {
   button: JSX.Element;
}) => {
   const { button } = props;
   return (
      <div>
         {button}
      </div>
   );
});

The problem is when the component is rendered, is rendered the string '[object Object]' instead of h1 element.

I would like to know what is the error I am making when passing a component as a property of another component.

As an extra info I try to print using console.log(button) in the child component and the output was:

JSXNodeImpl {
  type: 'h1',
  props: {},
  immutableProps: null,
  children: 'Hello world',
  flags: 3,
  key: 'bf_0',
  dev: {
    stack: 'Error\n' +

According to its document, the Slot has been used to replace for children in React which means instead passing an element, we just simply pass it as children with a q:slot property such as:

import { component$, Slot } from '@builder.io/qwik';

export default component$(() => {
   return (
      <div>
         <Slot name="button" />
      </div>
   );
});

// and this is where you use it
<Dropdown>
  <h1 q:slot="button">Hello world</h1>
</Dropdown>
