Cant get cable off my polaris winch?

I feel a little dumb asking this but I am replacing my steel cable with a synthetic rope. Ive only helped do this a couple times so maybe I’m missing something. the one’s Ive done the cable just comes off. Mine seems to be wedged or attached to winch. There is a small piece of metal wedged between cable and side of wheel. Ive tried pulling sliding and pushing that piece and nothing.

Ive googled this and most cables just come right off on video or they dont show them removing it.

I have an 2012 polaris sportsman pursuit with a polaris winch. Pretty sure its a 3500.

Any ideas
