Tab groups with multiple parallel routes (at starting path)

[m-salman-afzal]

I have a directory structure like this:

a/
    layout.tsx
    @b/
        page.tsx
    @c/
        d/
            page.tsx
        e/
            page.tsx

where layout.tsx could contain:

import type {FC, PropsWithChildren, ReactNode} from "react";

interface IProps {
    a: ReactNode;
    b: ReactNode;
}
const Layout: FC<PropsWithChildren<IProps>> = (props) => {
    return (
        <>
            {props.a}
            {props.b}
        </>
    );
};

export default Layout;

So, my question is, should I be able to get the render from slot page b and slot (c) pages d or e (depending upon the route which could be a/d or a/e). Note that I want the page from slot b to appear on both cases. As it stands now, I get 404.
If I put a page.tsx at slot c, it renders only that page and not anything else.
