How to create type-safe links route parameters with TanStack/Router and MUI?

Question

I am trying to use tanstack-router with the MUI Link component.

When I try to use the MUI component with a route that accepts a parameter, I get a compile error about Type '{ itemId: string; }' is not assignable to type 'Omit<never, never>'.

How can I structure my code so that TypeScript understands the parameters for the route?

Note that the MUI Link appears to function correctly, it just doesn't type-check.

The target route I'm trying to link to looks like:

export const itemViewRoute = new Route({
  getParentRoute: () => rootRoute,
  path: 'item/$itemId/view',
  component: ViewItem
});

export function ViewItem(){
  const params = useParams({from: itemViewRoute.id})
  return <>
    <SmallContentMain>
      <ContainerCard title={`View Item ${params.itemId}`}>
        <TextSpan>Description: "description of {params.itemId}"</TextSpan>
      </ContainerCard>

    </SmallContentMain>
  </>
}

I can link to the route with the TanStack Link and the type checking works fine, but the created link is not integrated with MUI (styling, functionality, etc.):

<ListItem>
  <RouterLink to={itemViewRoute.to}
    params={{itemId: "42"}} search={{}}
  >
    View Item 42 (RouterLink)
  </RouterLink>
</ListItem>

When I try to use the MUI Link, like this:

<ListItem>
  <MuiLink component={RouterLink}
    to={itemViewRoute.to}
    preload={'intent'}
    search={{}} params={{itemId: '42'}}
  >
    View Item 42 (MuiLink)
  </MuiLink>
</ListItem>

I get a compile error:

Following the MUI section on routing, I've customised the theme to integrate MUI with router:

export const LinkBehavior = React.forwardRef<
  HTMLAnchorElement,
  Omit<RouterLinkProps, 'to'> & { href: RouterLinkProps['to'] }
>((props, ref) => {
  const { href, ...other } = props;
  // Map href (Material UI) -> to (react-router)
  return <RouterLink ref={ref} to={href} {...other} />;
});

const muiLightTheme = createTheme({

  components: {

    MuiLink: {
      defaultProps: {
        component: LinkBehavior,
      } as RouterLinkProps,
    },
    MuiButtonBase: {
      // should be something like `as RouteButtonProps`?
      defaultProps: {
        LinkComponent: LinkBehavior,
      },
    },
...
