Did I damage ribbon while trying to remove gluey loudspeaker

I dropped my S21 5G a month ago and found out that my charger daughter board did not work anymore. Everything else was fine about my phone.

This is my first major repair, and while I was trying to follow the steps. I figured that the refurbished shop I got my phone at, used a *** ton of glue. And now I can't easily remove the loudspeaker. In every video and the tutorial on this website it seemed really easy.

Now I see that I at some point poked a bit into the battery with my plastic tool, and also scratched a bit of the ribbon cable. Should I buy a new ribbon cable and some isopropanol alcohol? Im really scared im going to break something, but I think im really close to fixing my phone again haha.

Thanks for the help in advance!
