feel free to do your own research.

Gnome (GTK4) doesn't have maximize / minimize buttons so you need to take extra steps to enable the behavior

This is controlled by the gtk-decoration-layout GTK setting key. Read its documentation for more. Instead of editing the GTK 4 .ini settings file, you can also run gsettings set org.gnome.desktop.wm.preferences button-layout <layout> to change your button layout instantly across all apps (where <layout> is your desired layout string).
