the boolean parameter is right click I believe.
mouse.click(false) left clicks
mouse.click(true) right clicks
as for interacting with the menu option, if you log in and bring that menu up in the osbot client and enter interface debugger mode, you'll have to mouse over the interface you wish to click and it'll tell you the parent and child Ids which u can then use in a line such as
interfaces.interactWithChild(int parentId, int ChildId, action)
eg
interfaces.interactWithChild(300,3,"Yes")
