Extension Class Structure

Here we provide an example structure, of course, you can modify it according to your needs.

class UIExtension extends PLExtension {
  constructor() {
    // You can set the id of the extension here, the default preference etc.
    super(...)
  }

  async initialize() {
    // Listen to events and modify UI here
      this.disposeCallbacks.push(
          PLAPI.uiStateService.onChanged("...", (newValues) => {
              PLAPI.uiSlotService.updateSlot(...);
          }),
      );
      ...
  }

  async dispose() {
    // Cancel event listening here
    for (const disposeCallback of this.disposeCallbacks) {
      disposeCallback();
    }
  }
}
