How to fix T480s/T490 keyboard connector (images for context inside)

Hey everyone. A while ago I ordered a keyboard from ebay for my T480, but I failed to notice that the one I got was for the T480s, therefore not compatible with my laptop. In the process of checking it out I lifted one of the connecting tape thingys (idk what theyre called) and some of the black plastic covering on the back of the keyboard ripped a bit. Its completely unused and new otherwise, and just been sitting in its packaging since then.

A few weeks ago I came across a local shop that also has some thinkpad stock, and I'd like to see if they'll buy it off my hands. I want to repair it first though, and the obvious first thought for someone inexperienced like me is to use some kind of glue. I didn't do anything yet, so here I am asking for advice. Would using some kind of super glue cause any issues? If yes, what is a good way to repair it?
