How can I use a Chrome extensions API that can be used with a callback function, such as chrome.identity.getProfileUserInfo, in chrome.webRequest.onBeforeRequest?

For example, I have a part of script similar to:

chrome.webRequest.onBeforeRequest.addListener(
  function (request) {
    return { redirectUrl: `https://example.com` };
  },
  // filters here. 
  // permissions here. 
)

The above works, it redirects request attempts to the https://example.com.

But the following, with wrapping the code in a callback function, the return/redirectUrl part is ignored and it doesn't work; it doesn't redirect.

chrome.webRequest.onBeforeRequest.addListener(
  function (request) {

    chrome.identity.getProfileUserInfo(function (profileUserInfo) {
      console.log(profileUserInfo.email);

      return { redirectUrl: `https://example.com` };
    });
  },
  // filters here. 
  // permissions here. 
)

This is a synchronous way that webRequest.onBeforeRequest is only capable of, correct? I use these callbacks, synchronous way because I learnt the chrome extensions API doesn't support an asynchronous way (e.g. async/await, Promise) as I asked on SO other day: javascript - async in chrome.webRequest.onBeforeRequest? - Stack Overflow

So, is it possible, to use chrome.identity.getProfileUserInfo in chrome.webRequest.onBeforeRequest? Thanks.
