To open a menu item in a new tab, check Open link in a new tab on that item. You can do this on the Menus screen or in the Customizer. In a block theme, use the Open in new tab setting on the link.
The menus you see depend on your theme. A classic theme shows Customize in Appearance, plus Menus and Widgets when it supports them. A block theme shows Editor in place of Customize, unless the theme or a plugin adds Customizer settings. It shows Menus or Widgets only when it supports them. Polestar, Ultra and the Puro theme are classic themes.
