Need help rebinding the Share button on my Xbox 1 Pro controller to take Screenshots and Captures in the Gamer Bar (On PC btw)

As the Title says, I'm currently trying to re-bind my share button so it can record and take screenshots again on my Xbox 1 Pro controller. I haven't been able to do so for a few days now, and have been trying to figure out how to get it to work again.

Any help is appreciated.
