Is there any way to configure "Super Key" to launch window overview, like in gnome?

I already tried the commands below for app launcher and it works.

    settings set org.gnome.mutter overlay-key "'Super_L'"
    gsettings set org.pantheon.desktop.gala.behavior overlay-action "'wingpanel --toggle-indicator=app-launcher'"

from here: [https://elementaryos.stackexchange.com/questions/1946/have-application-menu-open-up-with-only-windows-key][1]

But, what would be the command to replace "app-launcher" by "window overview"?
