How to use the @shopify/app-bridge/actions.Button.Action function in @shopify/app-bridge

const {appBridge} = this.props.polaris;
    if (!appBridge) return;
    const {breadcrumbs} = this.props;

    if (breadcrumbs != null && breadcrumbs.length > 0) {
      const breadcrumb = breadcrumbs[breadcrumbs.length - 1];
      const button = AppBridgeButton.create(appBridge, {
        label: breadcrumb.content || '',
      });

      const callback = !('url' in breadcrumb)
        ? breadcrumb.onAction
        : generateRedirect(appBridge, breadcrumb.url, breadcrumb.target);

      if (callback != null) {
        button.subscribe(AppBridgeButton.Action.CLICK, callback);
      }

      return button;
    } else {
      return undefined;
    }
  }
}

style,
  });

  if (action.onAction) {
    button.subscribe(Button.Action.CLICK, action.onAction);
  }

  const redirect = generateRedirect(
    appBridge,
    action.url,
    action.target,
    action.external,
  );

  if (redirect != null) {
    button.subscribe(Button.Action.CLICK, redirect);
  }

  return button;
}
