Show transfer progress

[vixalien]

When I share a file, I get this notification:

It would be nice if it would update frequently to show the state of the transfer. (Such as 30% done. ETA: 15 min)

Not sure if it's feasible though

It doesn't seem like the XDG Notifications spec or Portal spec have progress capabilities yet, but I agree it would be nice.

Another idea I've had (no time to implement), is a global ValentTransferManager as a GListModel I can just plugin into a list view. In that case, at least clicking the notification could open a GTK window with controls/progress.
