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

My binary runs in mac but the terminal window opens and I want to distribute it with an icon and maybe a nice .dmg image disk installer.

Is it possible to construct a solution with the existing API?

This feels like a whole other part of the fyne echo system if it doesn't already exist?

Describe the solution you'd like to see:

A whole documented system for how to release your final fyne binary on mac, windows and linux.

when I right click on a normal MacOS app I get "Show Package Contents" menu option and then all this inside the .app file ^

What's the process for distributing apps created with fyne to the Mac App Store?
