Need help to unpair NZW31 with Wink and add it to a different z-wave controller

I have a gen 1 (I think) switch that I bought in 2018 which has been working with WINK for 2+ years. I am planning on using Home Assistant (with a z-wave stick) for a DYI solution. I need help unpair (excluding) it from WINK network. I have tried removing the switch un-successfully so far.

Can someone please share the steps? Also, are there factory reset instructions on the switch? Can’t find anything on Google :wink:

Thanks!

Reset instructions on p 8.
