Facebook Marketing API：将图片上传到库提供了一个URL

I am new to the Facebook Marketing API and what I am working on is to upload an image to my FB Marketing library.

Right now, I can successfully upload an image to the FB Marketing but unfortunately I cannot see if there is a way to upload an image from a URL.

Has anyone had any previous experience with that ?

Code sample:

     Api::init(getenv('FACEBOOK_APP_ID'), getenv('FACEBOOK_APP_SECRET'), getenv('FACEBOOK_APP_TOKEN'));


    /**
     * {@inheritdoc}
     */
    public function testFunc()
    {
        $adAccountId = getenv('FACEBOOK_APP_ACCOUNT_ID');
        $account = new AdAccount();
        $account->{AdAccountFields::ID} = $adAccountId;

        $image = new AdImage(null, "act_{$account->id}");

        $image->{AdImageFields::FILENAME} = getenv('FACEBOOK_APP_MARKETING_PATH').'fbTestImage.png';
        $image->create();

        $this->line('Image Hash: '.$image->{AdImageFields::HASH}.PHP_EOL);
    }
