Navigation menu not showing

Hello, I am working on a staging site and seem to have accidently removed the navigation menu that was on top of each page. The page layout is set to Elementor Canvas for each page, but even if I change it to default, there is no navigation menu appearing. In appearance-editor-navigation, I created a header navigation menu, which is visible in the editor, but not when I view the individual pages. I guess the solution is easy, could you investigate please? Thanks
