Import sveltekit modules ($app/*) in private package in monorepo

[jameslounds]

I have a monorepo with a svelte components package. The package is not packaged by @sveltejs/package, I import them as a module and use directly, as in the Vercel Sveltekit Turborepo starter.
Is there a wayIi can import modules like $app/stores, or $app/navigation so my shared components can get the current url, or navigate to a page?
