Using MVMeter2 plugin in Premiere

I would like to replace the audio output monitor in Premiere to these analog PPM meters (as I am old and like analogue meters!) https://www.tb-software.com/TBProAudio/mvmeter2.html

I can get them working in Audition, but no joy in Premiere.  I have insert them as audio effects on my ouput channel in an audio track via  show/hide effects in the Audio Track Mixer window:

But the meters do not appear as they do in Audition.  Any suggestions what I might be doing wrong. or are they just not compatable with Premier?

Thanks.
