Every Electron ap is shown as “UNKNOWN”. I’m not sure about the details. I don’t know how bandwhich determines the process names, but utilities like top and ps shows Electron process names just fine.

To reproduce:

1. Start bandwhich
2. Install any Electron app and run it (e.g. Joplin, Spotify, Bitwarden)

Edit: This issue previously misidentified the cause as Flatpak. However, it turns out the root cause seems to be Electron apps (either running in Flatpak or unconstrained).
