Type safety for message responses?

[maybebansky]

In my content script Im sending a message to the background script in order to get the tab ID.

Content:

const { tabId } = await sendToBackground({
	name: "getTabId"
});

Background:

import type { PlasmoMessaging } from "@plasmohq/messaging";

const handler: PlasmoMessaging.MessageHandler = async (req, res) => {
  res.send({
    tabId: req?.sender?.tab?.id
  });
};

export default handler;

This is working but tabId has a type of any. Is there a way to get TypeSafety or do I need to manualy cast the type or use something like Zod?
