After battery replacement, home button not working: likelihood of fix?

Hi all, I completed the iPhone 7 battery replacement guide tonight but find that now my home button doesn’t work (the precise error message I get is about Touch ID not activating). If I re-open the phone, how likely is it that I will be able to re-enable the home button?

While I have read that it may be as simple as re-fastening the two display cables, I did have some trouble putting them in and worry I may have damaged the one that connects the home button.

Is there any way I can infer with greater certainty whether I can fix the button before I re-open the phone or is it more likely that I damaged the cables beyond repair?
