vaadin 14 - webcomponentexport doco is incorrect

The release notes for vaadin 14 show an example of embedding a vaadin app in another site.

The documentation shows the WebComponentExporter as a interface:

public class ExpertChatExporter implements WebComponentExporter<ExpertChatComponent> {
  public ExpertChat() {
    super("expert-chat");
    addProperty("user-context", null).onChange(ExpertChatComponent::onUserBrowsingContextChange);
  }
}

WebComponentExporter is actually a class.

The doco is also inadequate.

Thanks for the heads up. WebComponentExporter was an interface in earlier versions but was then changed into a class. Seems like docs are lagging a bit behind
