Context Menu - How to get selected row when user right-click

https://vaadin.com/docs/latest/components/context-menu

when user right-clicks on a grid to enter Context Menu . How can we get the selected row of the grid ?

Reason that with different rows we want to show different menus in the Context Menu.
