There are many ways to update your wallpaper. The easiest method is to right-click and select the option "Edit Wallpaper."
Or navigate to Settings and select the "Wallpaper" option. Once you choose it, the Wallpaper menu will open.
You can choose the img icon to select an image from the library or upload your own. You can also load images from a URL. If you don’t want to use an image, you can select the solid color wallpaper option by clicking the color icon. The Blur and Dim options allow you to modify the image’s appearance.
Additionally, you can set up an extra "Dark Mode Wallpaper" to switch styles automatically when you change between light mode and dark mode. This feature is optional.
