如何使用magento将动态url传递给gmail viewAction Go-to Action方法？

<router id="standard">
    <route id="mymodule" frontName="mymodule">
        <module name="Vendor_Module" />
    </route>
</router>

<?php
namespace Vendor\Module\Controller;

use Magento\Framework\App\Action\Action;
use Magento\Framework\App\Action\Context;
use Magento\Framework\View\Result\PageFactory;

class ViewAction extends Action
{
    protected $resultPageFactory;

    public function __construct(
        Context $context,
        PageFactory $resultPageFactory
    ) {
        $this->resultPageFactory = $resultPageFactory;
        parent::__construct($context);
    }

    public function execute()
    {
        // 获取动态URL参数
        $param = $this->getRequest()->getParam('param');

        // 处理传递给Gmail的数据
        // ...

        // 返回结果页面
        $resultPage = $this->resultPageFactory->create();
        return $resultPage;
    }
}

<router id="standard">
    <route id="mymodule" frontName="mymodule">
        <module name="Vendor_Module" />
    </route>
</router>

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <type name="Magento\Gmail\Model\Action\GoToAction">
        <plugin name="mymodule_gmail_gotoaction" type="Vendor\Module\Plugin\GoToActionPlugin" sortOrder="1" />
    </type>
</config>

<?php
namespace Vendor\Module\Plugin;

class GoToActionPlugin
{
    public function beforeExecute(\Magento\Gmail\Model\Action\GoToAction $subject)
    {
        // 获取传递给Gmail的数据
        $param = $_GET['param'];

        // 处理传递给Gmail的数据
        // ...
    }
}
