I have an app that is displayed like a status bar app (in Info.plist "Application is agent (UIElement) = YES").
I have added a TouchBar with Interface Builder and I added some Touch Bar Buttons items on it. The problem is that the custom touch bar don't show.
To make the custom touch bar to show I need to make the main WindowController window as Is Initial Controller true, unfortunately, by doing so, the app sows also a separate window with the same content than the popup window of the menu item.
Is there a way to implement a custom Touch Bar for a status bar macOS app?
