[Suggestion] add option to change system tray icon

[babrums]

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.

For now, with my current C# knowledge I can only modify and build the code locally, repeating the process after each new update
