Does Loopmash PLUG-IN work on audio in Cubase 12?

I understand the loopmash instrument was dropped in C12 but the Loopmash Plugin is still there and works fine in my project on an instrument track. However, I am trying to use it on an audio track (as Dom Sigalas does in his tutorial video) Create Vinyl FX, Stutters and CRAZY Chops with Loopmash FX! 💥💥💥 #cubase #loopmashfx - YouTube but it doesn’t have any effect when I press the effect buttons.

Am I doing something wrong or has Loopmash stopped working with audio please?
