How do I get the plasma icon back?

My plasma crashed, and I lost the plasma icon that used to be on top right corner, the one that if you left clicks it, it gives you a bunch of options such as “Add widget, and desktop setting, and configure plasma workspace, and zoom out”.

How do I get it back?

Right click desktop
Desktop Settings

In the Box by Desktop Activity: Type: Folder View or Default Containment
