I'm attempting to figure out if there is a simple way to find the custom properties of a rig in the dope sheet or graph editor. In the rain rig, for example, there is a custom property called "dummy eyes." I've set some keys on it, and I'd like to find those keys in the graph editor or the dope sheet. However I am unable to do so. I've looked through all the bones of the rig, making sure to hit alt-h in case there were any hidden bones and still could not find the attribute anywhere. Can anyone help with this?
Edit- I've added an image of the "character" subheader of the "Cloudrig" addon tab which contain the properties that don't appear on anywhere on the dope sheet or graph editor;
