Status bar icon and show/hide app through the icon

[lazakoa]

Is your feature request related to a problem? Please describe.

The official Spotify client doesn't play nice with the i3status bar since it has no icon to show/hide the application. After searching around, I determined psst has the cleanest gui but lacks the same feature. I want to be able to minimize and open psst by interacting with an icon in my status bar.

Describe the solution you'd like

1. Right-clicking the icon should bring up a small menu with the following options.

   • A button that shows or hides the application.
   • A button that lets you quit the application.
   • A pause/play button that stops or continues the current track. Nice to have.
   • A button to mute all sound coming from the application. Nice to have.

2. Left-clicking the icon should open or minimize the application.

3. It should work similarly to element-desktop, discord, and telegram.

4. I only considered it for the use case of the i3status bar, but realistically it should work the same way for any other status bar.

Describe alternatives you've considered
I have yet to consider alternatives since this feature exists in other applications.

Additional context

Above is an example I want without the menu that comes up when you right-click the application.
