Return "Access-Control-Allow-Origin" does not count for youtube v3 CORS

Question

I have a client and a server. My workflow is as follows:

• The server uploads the snippet to YouTube with the v3 API and receives a renewable URL (Youtube v3 API for renewable downloads - https://developers.google.com/youtube/v3/guides/using_resumable_upload_protocol )
• This URL is sent from my server to the browser, where the browser makes an ajax PUT request to download the actual file to the renewable URL.
• Thus, the file is not transferred to the server, but is directly downloaded from the client.

As a result, I get an error and the file could not be uploaded.

XMLHttpRequest cannot load https://www.googleapis.com/upload/youtube/v3/videos?key=mydevkeyanduploadid. 
No 'Access-Control-Allow-Origin' header is present on the requested resource. 
Origin 'http://localhost:3000' is therefore not allowed access. 

This is an ajax request:

var ajax = $.ajax({
    url: options.url,
    method: 'PUT',
    crossDomain:true,
    contentType: options.file.type,
    headers: {
        'Authorization': 'Bearer ' + options.accessToken,
        'Content-Range': 'bytes ' + options.start + '-' + (options.file.size - 1) + '/' + options.file.size
    },
    processData: false,
    data: options.file
});

The browser sends an OPTIONS request, which looks like this:
