Then, when you create a new page, give that page the unique name and the SEO URL should simply have the same name, but just to make sure you get the right code, click on the page icon to the left that opens the pages menu, then click on the small 3 dots to the right, then on SEO, then scroll down to where you see the SEO extension, this will be the code that you need to put into the box in order to navigate to the page (the unique code that you will give to the user)
See the attached image where it says ‘home’ - this is where you will find the unique code
