   * Launches **playwright** and launches a browser instance with given arguments and options when specified.
   *
   * This method uses the playwright's native {@link BrowserType.launch | launch} method under the hood and adds some functionality for applying fingerprints and proxies.
   * Before launching, the parameters that you specified using the {@link useProxy} and {@link useFingerprint} methods will also be applied for the browser.
   *
   * The options for are the same as the built-in ones, with a few exceptions that can break things.
   * For example, you can't use the `channel` option and will get an error when trying to specify it because the plugin doesn't support it:
   *
   * ```js
   * // This code will throw an error:
   * await plugin.launch({ channel: 'chrome-canary' });
   * ```
   *
   * You can get a list of unsupported options by importing the {@link UNSUPPORTED_OPTIONS} variable.
   *
   * If you need more information on how the native method works, use the **playwright** documentation -
   * [link](https://playwright.dev/docs/api/class-browsertype#browser-type-launch).
   *
   * @remarks
   * **NOTE**: This plugin only works with the `chromium` browser, which comes bundled with the plugin.
   * You will not be able to use default `chromium`, `firefox`, `webkit` and other engines that come with the **playwright** framework.
   *
   * If you need to use the default browsers without fingerprint spoofing, just use the **playwright** built-in `launch` method.
   *
   * You must specify the service key to apply the fingerprint when launching the browser (if the fingerprint was obtained using a paid key).
   *
   * @example
   * An example of launching the browser in visible mode:
   *
   * ```js
   * const browser = await plugin.launch({
   *   headless: false,
   * });
   * ```

   * @returns Promise which resolves to a browser instance.
