Replacing push button on toilet - Help!

niceguyed

Hi everyone, I know this should be a really simple fix but I've never done it before and just want to check it's as simple as I hope. Feel a bit embarrassed to call a plumber on this. Here's a pic of my system, plaster collar is snapped.



I was going to replace with this:

Or this:

Is it just a case of unscrewing the mount and pull the cable release away from the push button? I'm just trying to work out how it attaches to the two plastic arms in the pic.

Thanks so much!

I just clicks over but will take a bit of force to remove it, the 1st one from Amazon looks the closest match
