Accept any type that satisifies that other type in function

Is there like

type AWithFields = {
  foo: string
}

const mapper = <T satisifies AWithFields>(param: T) => {
  // update param fields here and return
  return param
}

type AWithFields = {
  foo: string
}

const mapper = <T satisifies AWithFields>(param: T) => {
  // update param fields here and return
  return param
}

I wanted to accept any param that satisifies AWithFields in the function.

const mapper = <T extends AWithFields>(param: T) => {
  // update param fields here and return
  return param
}

const mapper = <T extends AWithFields>(param: T) => {
  // update param fields here and return
  return param
}
