GSConnect
A GNOME Implementation of KDE Connect, integrates well with GNOME Files (nautilus) and the browser extension just with installing the extension.
You can easily manage GNOME extensions with Extension Manager.
Then for the Nautilus integration plugin the nautilus-python package:
sudo dnf install nautilus-python
Duplicated context menu entry in Nautilus
The extension comes with the nautilus extension, so if you installed the GSConnect extension through dnf you may have duplicate items.
Just remove nautilus-gsconnect installed with dnf and stick with the extension provided scripts.
