RV Menus in Gnome and Nautilus support

Hi ! Guys ! After some years I’m back to Linux for a new project.
Can someone share your Gnome rv.desktop files and icons, and a quick tutorial to setup them up, preferably without root, including rvlink protocol support and Nautilus support for opening supported files by double clicking and Open With, I can see rvfile.icns icon file inside resources but no idea how to set this up, so it works similar to win or mac.

I see a bash script inside bin but these only setups the rvlink protocol support and not Nautilus or Gnome menus setup. Thanks!!
