How to infer types from input?

example: publicProcedure
    .input(z.object({ names: z.array(z.string()) }))
    .query(({ input }) => {
      return input.names.reduce((acc, name) => {
        return {
          ...acc,
          [name]: Math.random(),
        };
      }, {});
    }),

  const { data } = trpc.router.example.useQuery({
    names: ["Hello", "World"]
  })

  // infer types from query input / autocomplete
  const { Hello, World } = data
