New Core One extruder jammed, and cannot find how to open idler cover

After a few successful prints with my new Prusa CORE One, I printed a larger print last night. This morning it appeared that the last 20% or so was not printed, even thought the printer reported the print as successful. It became soon clear that the extruder is no longer extruding and just making clicking noises. Based on reading existing posts and trouble shooting, I should be opening the idler cover and see if there's filament scraps to remove. However, it seems covered with this black shroud that I can't seem to remove whatsoever. There seem no screws connected, and pulling in various directions didn't do much. I don't want to break things, how do I proceed?

OK, I now understand that that cover should remain in place, and the idler cover is directly in front. Duh...

However, I opened this and try to see if anything was stuck / any debris, but am unsure on what I'm seeing. See attached.
