There is two-way communication between host and web component via web component's properties and events. If this doesn't answer your question, please elaborate more what you want to achieve.

Just like the useImperativeHandle hook in react, can expose the methods of components.

eg.

class MyElement extends HTMLElement {
  ...
 
  doSomething() {
    // do something in this method
  }

const element = document.querySelector('my-element');
element.doSomething();
