How to crush Victor on controller?

I'm playing with an Xbox controller on PC and I can't figure out how to crush Victor. I briefly got an on-screen prompt that I think said to either use LB or LT, but neither of those seemed to work when I tried them, and also both of them are mapped to running/crouching, so I ran and crouched when I pushed them. What's the proper way to do it?

  • (Not an actual answer) on PC it is the same generic M1 button your press to repair gens, cleanse totems and so on. It is likely that Xbox controls have a similar pattern.
