You don't need to install 2.8 ➤ Krikor gave you the answer for GIMP 2.10, the very same GIMP that you have declared in your first post.
Also about this specific function, there are no difference between 2.8 and 2.10 as shown in your screenshot, the "+" and the "<" (little arrow) are at the very same place
