Checking the code behind Nautilus context menu

In Nautilus, there is entry that can send files directly via Zorin Connect

How can I see the code that made this menu entry. My purpose behind this is to make similar context entry in Thunar.

Extra points if I can add it under a sub-menu like this one. (Send to mobile device -> SM)

I know how to do this in Thunar for KDEConnect, but not sure about ZorinConnect...

Whatever we could do with KDE connect, we can do with Zorin Connect by appending code to /usr/share/gnome-shell/extensions/zorin-connect@zorinos.com/service/daemon.js instead of kde-connect-cli
