Is it possible to create custom HTMLElement using class?

Whenever I'm creating unknown element, the constructor is unknown element (obviously).

document.createElement("hello");
// return value: <hello></hello>
// constructor: HTMLUnknownElement

Can i create my own HTMLElement using class?

class HTMLHelloElement extends HTMLElement {
  //...
}

document.createElement("hello");
// return value: <hello></hello>
// constructor: HTMLHelloElement
