     * A token URL or a token request function.

     * As a string, it should be a URL to the security token endpoint in your application.
     * The role of this endpoint is to securely authorize
     * the end users of your application to use [CKEditor Cloud Services](https://ckeditor.com/ckeditor-cloud-services) only
     * if they should have access e.g. to upload files with {@glink features/file-management/ckbox CKBox} or to use the

     * As a function, it should provide a promise to the token value,
     * so you can highly customize the token and provide your token URL endpoint.
     * By using this approach you can set your own headers for the request.

     * ```ts

     * 		cloudServices: {
     * 			tokenUrl: () => new Promise( ( resolve, reject ) => {
     * 				const xhr = new XMLHttpRequest();
     *
     * 				xhr.open( 'GET', 'https://example.com/cs-token-endpoint' );
     *
     * 				xhr.addEventListener( 'load', () => {
     * 					const statusCode = xhr.status;
     * 					const xhrResponse = xhr.response;
     *
     * 					if ( statusCode < 200 || statusCode > 299 ) {
     * 						return reject( new Error( 'Cannot download new token!' ) );
     * 					}
     *
     * 					return resolve( xhrResponse );
     * 				} );
     *
     * 				xhr.addEventListener( 'error', () => reject( new Error( 'Network Error' ) ) );
     * 				xhr.addEventListener( 'abort', () => reject( new Error( 'Abort' ) ) );
     *
     * 				xhr.setRequestHeader( customHeader, customValue );
     *
     * 				xhr.send();
     * 			} ),
     * 			...
     * 		}
     * 	} )
     * ```
     *
