How to get "send/share via gsconnect" actions on nautilus actions in ubuntu 20.04?

Solution 1:

Yes, a right-click entry called "Send to Mobile Device" is available.

I'm using Debian 10 with 3.30, and installed this Gnome-shell extension

I don't remember of any additional installation, but try to add nautilus-sendto too if required.

Note that your smartphone should be connected to the same wifi network and paired in GSConnect

EDIT: you may need to restart Nautilus to see this new entry
