This is disabled by default per the request of the Signal developers, because system tray support is not stable. Set to `false`, Signal will stop when you close it and will not have a system tray icon. Set to `true`, Signal will minimize to tray wen you close it, and will have a system tray icon on supported desktops. |

 You can change Snap configuration by running `snap set signal-desktop <key>=<value>`. For example, `snap set signal-desktop tray-icon=true`.
