Extension of the rear middle armrest for comfort seats

Hello all, I’ve messed up my middle armrest back after I’m so satisfied with the quality of my seats (especially since that doesn’t seem to be a matter of course) last week I was carrying the daughter’s birthday present in the back seat. A huge beanbag that doesn’t have solid edges… so nothing can happen…sigh…I forgot the zipper, which then drilled into the armrest over a few days. You in the photos. My question now. Even if it is not a hole, then I will probably have nothing left but to give the back to a saddler. So it should not remain in any case. Does anyone have experience of you with the removal of this backrest? Is this possible quickly? Can you get a document somewhere in which this is described? Of course I am also grateful for any tip that might help to get the leather back as it was before. I am especially disturbed that it no longer glat I’m going to go to the WE once with a leather care..maybe I get it smoothed out…but I don’t believe it. Thank you very much
