How can I make a direct fetch on a router endpoint from TRPC in NextJS on client?

In the documentation you can use the vanilla TRPC client like this:

const bilbo = await client.getUser.query('id_bilbo');

But with NextJS app is wrapped with the WithTRPC wrapper. where you can only use hooks. How can I make a direct call?
