js-objectdetect Javascript plugin implementation

I'm a design student working on a college web project that requires implementation of gestural technology. While looking through plugins online, I came across js-objectdetect.

The project in question is a decision-making game that uses gesture-based controls using a webcam. So, with minimal knowledge of JavaScript, I've been trying to figure out how to implement the plug-in and create functions to click on buttons and drag objects.

I would really appreciate it if someone could help me understand the plug-in or provide an ELI5.

I've tested the demos provided with the plug-in. They've worked on Firefox and give me a WebRTC error on Chrome. Thanks
