Yes, it works on the latest stable release. They work either on WebGL and WebGPU. If you face issues you can always ask for support in my discord channel.
There's no need to add a demo for each plugin type, effects work on the textures rendered, regardless of the plugin.
In this video I use my drop shadow extensively. You can scroll to min 2:20. Note the progress bar mesh, drop shadow is being rendered for the whole UI. This is a 2D set of effects.
