I can’t find out how to use the Simplify Curve add-on on animation F-Curves in Blender 2.8.

I’ve activated the add-on, and in the 3D view the parameters are changeable when operated on a curve object. But when I select keyframes and activate Graph Editor ➔ Channel menu ➔ Simplify F-Curves, I can’t find the settings (Error Value) anywhere.

Thanks in advance for your help.

Sounds like unfinished implementation, but there is a workaround for the time being

Don't use the menu to call the operator, call it from the F3 Search Menu while hovering the 3D View, not the F-Curve Editor

enter image description here
