Plexamp and its poster

I have a lifetime Plex subscription. I’ve tried Plexamp, but I have a question. When I add a music folder, it recognizes it, but it shows a generic cover or poster. For example, if I have a folder of Portuguese music, it uses the same first cover for all the songs by default. In other players, like Navidrome, I can see the cover art for each individual song. I should mention that my music collection has embedded artwork in each file. Could you please tell me how I can fix this? Thank you.

Plex has only support for album art, not for track art.
