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.
