+`System Preferences > General > Login Items & Extensions` (macOS 13+)
+
+

+I am still searching for a way to keep the menu open after click (if you know of a way, let me know!).

+Though, admittedly, this is for experts only.
+I still have to find a nice user-friendly way to achieve this.

+You can hold down option key before opening the menu bar icon to show hidden articles regardless.
