Right click mouse events not firing on Mac?


I have a bit of an issue. In my game I’m using the right mouse click to fire a grappling hook. On my Windows machine, this works just fine. But I just built a Mac version and tested it out on my old laptop, and the right click doesnt do anything in the game. I first thought it was just my old Mac finally dying out on me, but the right click definitely works in other parts of the operating system.

Is this a known issue? I’ve tried searching for similar topics but I’ve not found anything.
