React: Property 'Item' does not exist on type

Question

Trying to resolve this tsconfig issue but unsure how to proceed:

Property 'Item' does not exist on type '{ ({ children, spacing }: { children: any; spacing: any; }): Element; propTypes: { children: Requireable<ReactNodeLike>; spacing: Requireable<string>; };

Basically I have the element called Stack that looks like this:

const Stack = ({ children, spacing }) => {
      const items = findChildrenByRole(children, 'Stack.Item');

  return children ? <div>{items}</div> : null;
    };
    
    Stack.propTypes = {
      children: T.node,
      spacing: T.oneOf(['none', 's', 'm', 'l']),
    };
    
    Stack.defaultTypes = {
      spacing: 'none',
    };
    
    export default Stack;

I think have an ìndex.js file like this:

import Stack from './Stack';
import Item from './SubComponents/Item';

Stack.Item = Item;

export { Stack };

I use it like this:

<Stack spacing="s">
  <Stack.Item>
    Item
  </Stack.Item>
</stack>

How do i make it understand that Item exists in my vscode?
