How to get a home button working?

I have an iPhone 8 plus that I bought as a project to fix and get going again, then possibly sell. I have ordered most parts, except for the back glass (hard to find a product red OEM one for a decent price..), and the parts have started arriving now.

However, I’ve been doing some reading on the home button. I have the original button, but not the connectors/flex cables. Is there any way to get a working home button? Would it work if I got an iCloud locked 8/8 Plus and stole the home button? i’m aware touch ID wont work, I just need a functioning home button. I will continue with my own research, but any help would be appreciated.
