evert I'm using Solus Gnome 3.32 edition (this won't apply to Budgie fyi), and I have Gnome Tweaks app installed so I can use Gnome Extensions to alter my Gnome Shell experience. The extension to change the top left from the default which was "Activities" into an icon instead was with the help of this extension located here: Activities Configurator Extension
The extension website comes in handy if you ever need to tweak the desktop. If you change the icon and it doesn't show up, you might have to restart the shell for it to show. Just hit Alt+F2 and then type the letter "r" and hit enter. It's a command to simply reload the desktop, you won't lose any work or anything like that, it's just a quick workaround instead of restarting or logging out and back in to get it to load. Good luck and hope that helps some!
