Drumline

Is there any way that the MuseScore Drumline extension that existed on MuseScore 3 can be downloaded onto MuseScore 4? The Drumline extension had it all! MuseScore 4 doesn't seem to have all the different drums, and various types of notation symbols that was on the Drumline extension.
I write a lot of Drumline music and the Drumline extension has been getting me through for a long time now. Is there any possible way of getting it back?!
