Touch not working after screen replacement

I replaced the screen on my 40mm iWatch Series 5 and the screen shows everything correctly post repair, but I cannot get the screen to respond to my touch at all and can't get past the security code.

While repairing I wasn't sure if I had damaged the force touch sensor gasket, so I tried to install a new one. I was not at all confident of that part of the repair. The kit came with the force touch gasket sensor and a couple of the adhesive seals for either side of the gasket. The repair video doesn't go into any detail about how to apply these and after I had put one of the adhesive layers down on the cleaned case bottom rim, then the force gasket, then another layer of adhesive and finally the screen, it didn't seem to fit very snugly in the case and appeared to be riding a little bit above it. I can easily open the case with a fingernail after the repair, so pretty sure there is too much between the case bottom and the screen.

Does anyone have clearer instructions for replacing the force touch sensor and related adhesive?

Also is there any information on the three connectors from the motherboard to the display? The middle one on mine under a loupe looks a little sketchy. Could that be another reason the touch screen is no longer responding correctly for me?

Thanks in advance,
