Project with PeppyMeter/PeppySpectrum Screensaver Plugin for VOLUMIO

I’ve been trying the new version for a week but I’m having trouble installing the display and then with peppymeter-basic.
that is, I managed to put everything in but my display is small (3.5" hdmi) and I can’t change the size of the text or graphics like I did with the contemporary plugin used on version 2.9. I looked for help in different sections but I received no solution.
