Caching vimeo private videos on cache using service worker

Question

So I created an offline functionality for my webapp. There's a function that is fetching a list of url to save it on the cache storage so that it will be available offline for later use.

this is where I pass the urls to the service working using a postmessage event

zigFilesToCache = filteredArray
zigVideoToCache = videoToSave

if ('serviceWorker' in navigator && navigator.serviceWorker.controller) {          
          navigator.serviceWorker.controller.postMessage({ videoUrls: zigVideoToCache, token:token });
        }

And this is the event listener that I have on the service worker

self.addEventListener('message', event => {
  const message = event.data;

  if (message.videoUrls) {
    console.log('uls are fetching')
    const urlList = message.videoUrls;
    const token = message.token
    const promises = urlList.map(url => fetchAndCacheVideo(url, token));
    
    event.waitUntil(
      Promise.all(promises)
        .then(() => {
          console.log('successfully cached')
        })
        .catch(error => {
          console.log('caching error', error.message);
        })
    );
  }
});

And this is the fucntion for fetching the urls

function fetchAndCacheVideo(request, token) {
  console.log('caching video', request)
  const videoId = request.substring(request.lastIndexOf("/") + 1);
  const apiUrl = `https://api.vimeo.com/videos/${videoId}`;

  return fetch(apiUrl, {
    headers: {
      Authorization: `Bearer ${token}`
    }
  }).then(response => {
    if(response.ok) {
      const responseClone = response.clone();
      caches.open('videos')
        .then(cache => cache.put(request, responseClone))
    }
    return response
  })
  .catch(error => {
    console.error('Error fetching and caching videos:', error)
    throw error
  })
}

The problem is if I don't declare the api where I want to fetch, it will return a CORS POLICy ERROR. At first I thought it has something todo with the token authorization and I created an api to fetch the token from vimeo. Though And for this one, I was able to cache the response, I can't display it on the UI.

This is the response from the fetch that I can now save within the cache storage

The video url is like this "https://vimeo.com/videos/431313879", so I was expecting it to be displayed even if the user is currently offline since I was caching the video using the service worker.
