According to this there is a Beta build that you could try if you wanted: https://kubuntu.org/news/plasm...eta1-available-for-testing/
But like they say, since it's in Beta you might want to wait for their next official release which I think is scheduled for October.
That’s not quite right. It’s not rdping into a Windows machine to use apps. This had existed in the past as RemoteApp where just the virtualized app(s) is/are presented to the user and not a full vm.

Im guessing they just made the process easier now and are treating what they killed off as something new.
