5. Once the duplicate theme is created, click on "Explore free themes" or "Visit Theme Store" to browse and select a new theme. You can also choose to upload a theme from your computer.
6. When you find a theme you like, click on the theme and then click on "Add theme" to install it.
7. After the new theme is installed, you can click on "Actions" and select "Publish" to make the new theme live on your store.
8. You can then customize the new theme by clicking on "Customize" or "Customize theme" in the Current theme section. Here, you can modify the layout, colors, fonts, images, and other aspects of the theme to match your brand and preferences.
9. Once you are satisfied with the changes, click on "Save" and then "Publish" to apply the customizations to your live store.

Note: Before making any changes to your theme, it's recommended to always create a backup or duplicate of your existing theme so you can easily revert back if needed.
