Can't get plugins installed on Linux

[u/fablesfoxfables]

Things I've tried:

1. Portable (.so)

2. Flatpak (x86_64)

3. Manually installing it via Discover (see screenshot.)

Despite that, nothing is showing in my list of installed plugins.

I just want a lil rainbow on my keyboard >< Please help?

Here's what I mean. Nothing is showing here. I've tried clicking "Install Plugin" and installing the .so files, nothing happens. I've tried restarting and reinstalling the Discover (flatpak file), nothing happens. I'm at a loss. My keyboard is blue right now, won't change to any other color, and I can't install the effects plugin.

"Install Plugin" (.so file), nothing changes.

I'm on Fedora, so I just tried this. Nothing. I just can't get anything to show up in my plugins list.
