Nextjs 12, 13 with geo in middleware

Hi guys,

I couldn’t find information on how to get the geo in the middleware. For example, a user go on the website and I create a cookie location: Canada or location: city

For now I tried, but no success. It’s always USx:

export default async function middleware(req: NextRequest) {
const { nextUrl: url, geo } = req;

const city = geo?.latitude ?? 'USx';

const res = NextResponse.next();
const supabase = createMiddlewareSupabaseClient({ req, res });
res.cookies.set('city', city);
