Native private methods in Node.js

Question

I run code from MDN example (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Classes/Private_class_fields#private_methods)

class ClassWithPrivateMethod {
  #privateMethod() {
    return 'hello world';
  }

  getPrivateMessage() {
    return this.#privateMethod();
  }
}

const instance = new ClassWithPrivateMethod();
console.log(instance.getPrivateMessage());
// hello world

in Node.js 14 and got error:

  #privateMethod() {
                ^

SyntaxError: Unexpected token '('

MDN contains info that private class methods are available from Node.js 12.0.0 Private fields works fine. I need same private methods. "use strict" turn on/off does not affect the error. Is there a way to make the documentation example work in Node.js?
