Хотел то же самое предложить, но пока в chat gpt переписывал вопрос на английский, вы меня опередили 🙁

Но, собственно, он то же самое, что и на русском, предложил

If your application is native and does not have access to a browser environment, then you may need to use platform-specific APIs to obtain the necessary device parameters for the data transfer protocol.

For example, on iOS, you could use the UIDevice class to obtain information about the device, such as the screen resolution, and the NSBundle class to obtain information about the app, such as the app version. On Android, you could use the DisplayMetrics class to obtain information about the device's screen, and the PackageManager class to obtain information about the app.

As for the browser-specific parameters, such as the user agent and accept header, you may need to create a custom implementation to generate this information based on the device and application data that you do have access to. There are also third-party libraries available that can generate a user agent string for your application, such as the "UAParser.js" library for JavaScript applications.

Overall, you will need to determine the specific APIs and libraries that are available for your platform and programming language, and use these to obtain the necessary device parameters for the data transfer protocol.
