I have a Wolverine Ultimate RZ06-0225 controller for Xbox and the right trigger started to stick and not work correctly.  I disassembled it and discovered the arm that attaches the trigger to the spring has broken.  Is there anywhere I can get a spare?

Note that when I researched this issue I found a post on Reddit where someone had exactly the same problem as me, and they’ve helpfully posted a photo that shows similar breakage.
