update circle thingy in redhat 8 gnome

[Siplus]

in gnome (or maybe kde too, i don't use it so i wouldn't know), redhat 8, there is this little circle that when you click on it updates (blue when your ok, green when it's doing something, red when you need updating). well, i accidently deleted it, so what do i have to do to put it back on there?

also: i have an annoying habbit of deleting things i put on my menubar (kinda stupid...but), is there a way i can 'lock' it so i can't change it?

right click on panel,,,go to add button and system tools. You should see it as "Red HAt network".
Click it and it will be added on your panel again.
