Disable WordPress Multisite Modifying Media URL

Question

I'm using DigitalOcean Spaces to store my static assets. All is working fine, my media library url point to my Spaces (e.g. foobar.sgp1.digitaloceanspaces.com).

The problem starts when I install multisite, as it's default WordPress behavior to add "sites/xxx" to all sub site's media url (e.g. foobar.sgp1.digitaloceanspaces.com/sites/2). Which of course, my assets are not there, and can't be found.

I've found this link:

https://wordpress.stackexchange.com/questions/307530/remove-multisite-part-from-wordpress-multisite-upload-directory

Which gave me an idea.

I've tried this on functions.php

add_filter('upload_dir', 'multisite_path');

function multisite_path( $param ){
    $path = str_replace('sites/2/', '', $param['path']);
    $url = str_replace('sites/2/', '', $param['url']);
    $param['path'] = $path;
    $param['url'] = $url;

    return $param;
}

But it's not working.

If there's a hook to remove "sites/2/" from the url, or any other way to disable this functionality, I'm open for suggestions.

Thanks.

Found the solution here:

wordpress multisite remove /sites/{ID}/ automatic upload url

Here's the working code:

add_filter( 'upload_dir', 'same_upload_dir' );
function same_upload_dir( array $uploads ) {
    $baseurl = WP_CONTENT_URL . '/uploads';
    $basedir = ABSPATH . 'wp-content/uploads';
    $subdir = $uploads['subdir'];

    return array(
        'path'    => $basedir . $subdir,
        'url'     => $baseurl . $subdir,
        'subdir'  => $subdir,
        'basedir' => $basedir,
        'baseurl' => $baseurl,
        'error'   => false,
    );
}
