Seems like a new budgie trash applet appeared ? v. 1.0.2+202107041619~ubuntu20.04.1
I can now delete folders in my configuration ( most of my usual personal folders are on another partition/disc, outside the root system ).
But this new applet has a static icon looking like a full bin - ie. does not show if trash is busy or empty.
