Hiding Page from navigation

I am using the Airi Pro theme. When I create a page, it also adds to the navigation menu at the top. How do i hide a page from navigation?

I have already tried to correct in the menu under customize (my menu is not the same).

I tried to add short code, didnt work.

I tried 2 plug ins. Didnt work. I don’t want the page to be private because it is a landing page after someone makes a purchase.

Hello,

Did you create a menu for your header?

Kind Regards, Roman.
