How to put Amazon Honor button on a page, not post

Hello, been struggling with this for a few hours. I want to put an Amazon Honor System button up on my About page only. Of course, it is in html. When I copy and paste the html in my about write page in the code tab, it doesn’t appear on the page, although I can see the outline of a small box.

Does anyone know why? Do I need special code for html to show up on a Page? Thanks!
