How do I make it show up on my website in google search?
They are called sitelinks, they are a collection of links that Google determines to be the most useful to help users navigate your website and locate the information they need the most. source: https://www.create.net/support/how-to-change-the-links-that-appear-under-your-site-on-google
Those are siteLinks, and I think google determines them automatically. You cannot do much to change those.
You cannot direcly influence sitelinks on Google. However, you can influence them indirectly. Sitelinks are displayed primarily of pages, that are linked from the main menu or are often linked internally.
