Enabling Sidecar

Now that Catalina and iOS 13 have been released, I'm using Sidecar to use my iPad as a third monitor on a constant basis. Since I also carry my iPad around, I'm connecting Sidecar several times a day. I know how to make a menu selection with KM (I've used KM a long, long time), but I've never needed to select a "status menu" item (the icons on the right side of the Mac menu bar). Is is possible?
