Is it possible to animate geometry nodes? I would like to insert the F curve from the sound into the Factor parameter in the Node editor (1.). But after adding the keyframe, I don't see this channel in the graph editor. (2.)

I don't know how to display this in the graph editor?
I tried to look elsewhere, but I didn't find anything. I am using Blender 2.92 RC version.
In Blender 2.92, parameters are not displayed in the graph editor.
They are displayed in Blender 2.93.
