Option to not show tray icon

[flying-sheep]

Is your feature request related to a problem? Please describe. I have too many symbols in my tray, and the tray icon fullfills no purpose that a menu bar or so can’t fullfill.

Describe the solution you'd like A Settings dialog as requested in https://github.com/IsmaelMartinez/teams-for-linux/issues/462 should be available with and without the tray icon, and have an option to hide the tray icon.

Describe alternatives you've considered None, I can’t hide the tray icon using my system.

Additional context Since https://github.com/IsmaelMartinez/teams-for-linux/issues/844 was interpreted as “Close app with ×”, and converted into a discussion, this issue is not a duplicate of it.
