How to get response type depending on the input params?

const example = <T extends unknown>(params: T): T => {
  return params
}

// TYPE: const params: readonly ["Hello", "World"]
const params = ['Hello', 'World']

// TYPE: const result: readonly ["Hello", "World"]
const result = example(params)

// TYPE: const str1: string, const str2: string
const [str1, str2] = result

// TYPE: const params: readonly ["Hello", "World"]
const params = ['Hello', 'World']

const { data } = trpc.router.model.example(params)

// I want the following type returned based on the params 
// TYPE: const result: readonly ["Hello", "World"]
const result = data;

// I want the same result as in the simple example
// TYPE: const str1: string, const str2: string
const [str1, str2] = result
