At Ubuntu 22.04 if you add apps to favorites, it will appear in the dock, but it will no longer be displayed in the menu. How to disable it? I used to deal with Ubuntu 16.04 and Ubuntu 20.04, so this innovation is very inconvenient for me.
You cannot directly. It is how the Application overview is designed to work in Gnome 40 and up.
The application overview gives an overview of the installed applications. The idea is that an application available for launching on the dash does not need to appear a second time on that screen. In a sense, that makes sense.
There still is a way if you still insist: Create a symbolic link (or just copy) of the .desktop launcher of the program you want twice in your ~/.local/share/applications folder, and give the link a different name, e.g. ~/.local/share/applications/firefox2.desktop. Firefox now will appear twice in your Application overview.
Working with a symbolic link rather than a copy ensures that the duplicate remains the same as the original if that would be changed by a future update.
