hc wont display types of a large hono app even after following docs

[IslamZaoui]

I have this hono app:

const app = new Hono<App.Env>()
	.post('/register', zValidator('form', registerSchema), async (c) => {
		const formData = c.req.valid('form');

		if (!(await isUsernameAvailable(formData.username)))
			return c.json(
				{
					success: false,
					error: {
						name: 'ERROR_USERNAME_TAKEN',
						message: 'Username already taken'
					}
				},
				400
			);

		const user = await createUser({
			username: formData.username,
			password: formData.password,
			role: formData.role
		});

		const sessionToken = generateSessionToken();
		const session = await createSession(sessionToken, user.id);
		setSessionTokenCookie(c, sessionToken, session.expiresAt);

		return c.json({ user, session });
	})
	.post('/login', zValidator('form', loginSchema), async (c) => {
		const formData = c.req.valid('form');

		const user = await getUserByUsername(formData.username);

		if (!user) {
			return c.json({
				success: false,
				error: {
					name: 'ERROR_USER_NOT_FOUND',
					message: 'User not found'
				}
			});
		}

		if (!verifyPasswordHash(user.passwordHash, formData.password)) {
			return c.json({
				success: false,
				error: {
					name: 'ERROR_INVALID_PASSWORD',
					message: 'Invalid password'
				}
			});
		}

		const sessionToken = generateSessionToken();
		const session = await createSession(sessionToken, user.id);
		setSessionTokenCookie(c, sessionToken, session.expiresAt);

		return c.json({ user, session });
	})
	.get('/logout', async (c) => {
		const { session, user } = c.var;

		if (!session || !user)
			return c.json({
				success: false,
				error: { name: 'ERROR_ALREADY_LOGGED_OUT', message: 'Already logged out' }
			});

		await invalidateSession(session.id);
		deleteSessionTokenCookie(c);

		return c.json({ success: true });
	});

export default app;

const app = new Hono<App.Env>()
	.basePath('/api')
	.use(
		cors({
			origin: '*',
			allowMethods: ['GET', 'POST', 'PUT', 'DELETE'],
			allowHeaders: ['Content-Type']
		})
	)
	.use(authMiddleware)
	.use(logger())
	.route('/auth', authRoute);

export type AppType = typeof app;
export default app;

the hc client is not displaying routes inside the auth route:
