So do I need to remove the home button at all if the new kit comes with it already built in? I don’t care about touch-id capabilities (it’s my daughters phone)

Ok so battery extraction went a little bad and ended up cutting into old battery. When I pulled it out it was smoking a little. Got new battery put in and everything back screwed. It's charging up now (I'm assuming the battery is shipped dead) so heres hoping I didn't kill my phone.
