When you open a new tab Ctrl+N in Google Chrome, you will see shortcuts of websites you visit often by default under the search box.
When you have Google set as your default search engine in Google Chrome, you can open a New Tab page Ctrl+N in Google Chrome and click/tap on the Customize button at the bottom to see the New Tab page customization menu.
Starting with Google Chrome 77, you can enable to use an updated second version of the New Tab page customization menu.
When you enable the second version of the New Tab page customization menu, it still allows you to change the Background of the New Tab page, but it adds a new Shortcuts menu that allows you to select to show My shortcuts, Most visited sites, or Hide shortcuts on the New Tab page in Google Chrome.
This tutorial will show you how to hide or show shortcuts on the New Tab page in Google Chrome.
