There is a thread on here (I think, sometimes I'm not sure if it is the Ioniq forum where I saw it) with perhaps five different methods of disabling the panic button.
The method described in the video is very similar to the method I used. You don't need "parts", I simply cut off about 2mm of a paper clip - I used a wire cutter but scissors will work fine - just be careful about the snipped piece shooting off. I spent a few minutes to attempt to align it, but it turned out not to necessary. It rolled under the cover and I discovered that blocking just one side (rather than two as the video shows and that I myself thought I would have to do) was enough. It won't trigger now, and the whole operation can be done in seconds - reversible should you sell the car.
