How to publish multiple pages project?

Can someone please let me know how do I actually publish multiple pages project so that when the next / previous page chevron icons (to the right & left) appears automatically when published?
I currently only have a single page published every time I click on publish and nothing to enable the viewer to go to the next page chevron icon. Perhaps it’s an obvious thing but have been looking around how to go about this…any tips would be much appreciated!

Hello! After you publish the website, you can go to Preview, and click Settings. You’ll see a button here that says “enable navigation arrows”.
