Activating in the Character Panel only the fonts from my own local library

I am trying to replicate an arrangement I've had on a 2015 iMac running Monterey, Illustrator 2020 and the then current FontAgent desktop application. Now using a new iMac 2024, Illustrator 2026, and the current Font Agent. I've loaded the fonts (all OpenType) and all of the ones I've activated in FontAgent are listed as expected in Illustrator's Character Panel..

THE PROBLEM: I haven't found the way on my new set-up to display ONLY the fonts activated in FontAgent. By some setting (or set of settings), I was able to hide all but the faces I use. I want to create the same ease, efficiency and convenience—100s of typefaces I'll never use are clogging the works. I'll be most grateful for any solution or advice.
