How to use a blocking request listener with manifest v3?

I am having trouble migrating my manifest v2 to v3.

Basically, my extension is downloading some files when a specific url pattern is matched.

I've migrated my old manifest to this:

"permissions": [
    "webRequest",
      "downloads",
      "notifications",
      "storage"
  ],
  "options_page": "options.html",  
  "background": {
    "service_worker": "background.js"
  }

However I still have this error:

Unchecked runtime.lastError: You do not have permission to use blocking webRequest listeners. Be sure to declare the webRequestBlocking permission in your manifest.

But I cannot add webRequestBlocking because then I get another error telling me v2 is deprecated.

I am using a blocking request listener in my service_worker file:

chrome.webRequest.onBeforeRequest.addListener(
    callback, {
    urls: ["<all_urls>"],

},["blocking"]);

How would I migrate that to the v3 manifest?
