I purchased Irina's Tool Ring System knowing it was for MV, but I saw another post on here when searching that said they use it on MZ so I assumed it would work. Worst case scenario, it wouldn't work and I just donated some money to a developer which I'm perfectly fine with. Anyways, I have the plugin installed, but it crashes my game upon loading the map and the DevTools window pops up. The console gives me this information"

This pops up in the game window as well: this[_0x4d6b(...)] is not a function

Is there something I can just tweak to get it to work on MZ? I haven't been able to find an equivalent plugin for MZ that will allow the player to easily cycle through tools. I use CAZ's farming+fishing+day/night plugin and they have their own thing which works, but it's one of those scroll through until you find the right tool thing and I prefer something like a tool ring/wheel as it tends to be snappier and more efficient.

Here's the Tool Ring plugin I'm using:
