Cannot press home button on iPad 7th Generation

I recently replaced a customer’s home button and digitizer on his iPad 7th Generation, but the home button does not work and I have the button and the bracket glued down but it just pushes it to the bottom of the bracket. It is still glued and it is also connected and the screen is on but I cannot go home because I cannot press it. I checked the guide regarding replacing the home button, but still can’t solve this issue. Can someone please help me? Thank you!
