Upgrading localized routing to v2

[MarkusKramer]

I'm trying to migrate a SvelteKit app to paraglide v2.

Previously it was possible to localize a bunch of static URLs easily with something like:

        "/about": {
            en: "/about-us",
            de: "/ueber-uns"
        },

see https://inlang.com/m/dxnzrydw/paraglide-sveltekit-i18n/localised-routing

Based on what's documented at https://inlang.com/m/gerre34r/library-inlang-paraglideJs/strategy#pathname-based-url-localization-example it's unclear how to combine having a URL lang prefix like /en or /de AND localized paths.

I've tried:

		paraglideVitePlugin({
			project: './project.inlang',
			outdir: './src/lib/paraglide',
			strategy: ["url", "baseLocale"],
			urlPatterns: [
				{
					pattern: ":protocol://:domain(.*)::port?/:locale(de|en)/:path",
					deLocalizedNamedGroups: { 
						"path": "about" 
					},
					localizedNamedGroups: {
						en: { 
							"path": "about-us" 
						},
						de: { 
							"path": "ueber-uns" 
						},
					},
				},
			],
		}),

Opening any page e.g. /en/about-us results in a 404 however.

How to migrate the old config?
What is the expected behavior if no url pattern matches?
Also can I still expect links in svelte components like /about to get automatically localized depending on the current locale?
