You can install blur my shell extension to modify the look.

if you want blurred backgrounds, the extension blur my shell will work.

Why don't you just look at the source code? https://github.com/aunetx/blur-my-shell

Blur my Shell - Blurs the background in the overview.

dnf install gnome-browser-connector Firefox extension: {addons.mozilla.org} - Resource Monitor • Show system resources in the top bar - User Themes • Custom themes (may break some things) - Dash To Dock • turns the application launcher into a macos style dock - Blur My Shell • make the UI glassy

In my case, I'm using the Blur My Shell extension, so it basically takes whatever background image I have and places it in the overview with a blur effect (though you can also remove the blur completely and just use the extension to set your background as your overview background). By default it will blur a lot of things around your desktop, like the top bar, for instance— just disable anything you don't want; I personally only leave the Overview blur active.

I pretty sure there are some extensions like https://github.com/CorvetteCole/blur-provider and this https://extensions.gnome.org/extension/3193/blur-my-shell/ but they're not completely usable IMO. KDE has a lot better options if you need to play around with blur.
