Last & next button

When reading stories, I’ve noticed that there are ‘Next’ and ‘Prev’ buttons, appearing as a small arrow shaped button at the bottom of choices. How do you create those buttons? I don’t like the look of next or previous buttons the same size as the normal choices. If someone could help, that’d be wonderful!

Use this code next to the choice, it will automatically create pages for you

Thank you!
