Chosen Solution

So I was taking apart this new used battlefield 1 limited edition Xbox one s to clean it and well when I opened the bottom part and the sync button fell out the front and I can’t find it so how can I replace that and also I’m not talking about the little soldered button I’m talking about the plastic piece that pokes that

Okay so I fixed it by taking a Xbox one controller sync button and putting it in there with a few modifications lmao I stuck a cut up quetip in so it can click the button and duck tape as my adhesive and now my Xbox syncs controllers with no problem
