Adding worskspace switcher to the linux

Somehow in my linux vcn, the workspace switcher icon stopped showing up. For each poject, I had to open a new vnc session, else keep all files opened in the same workspace.

Finally got the solution:

In the linux home, write click on the lower most tab gives the below options. In the "Add to Panel" option, there is specific "Workspace Switcher" option. Just add it !!
