I tried to share a folder from windows to Ubuntu, but I couldn't find the 'devices' option in the menu bar. Then I followed the instructions at https://askubuntu.com/a/911703/1681337 , but now all menu bar is missing. Here I attached a picture of my Ubuntu desktop and a some information. I had a hard time interpreting some words like Unity and Compiz.
Device name: ngs2468
Gnome: 3.28.2
