[Suggestion] add option to change system tray icon

Is your feature request related to a problem? Please describe. Tray icon is almost indistinguishable from the Telegram tray icon.

Describe the solution you'd like Having the ability to replace or customize the tray icon, for example, by allowing users to edit the gui-config.json file or by providing a context menu option. Maybe just an option to change tray icon color

Describe alternatives you've considered While there is an alternative option of using third-party software to manage tray icons, it seems unnecessary and far from an ideal solution.
