How to properly use Ninja Riper for Sketchfab?

Question

Game development

Colleagues, good afternoon!
Can you please tell me how to cut a model from Sketchfab using Ninja Riper?
If possible, step-by-step instructions, otherwise, no matter how I try, nothing happens.
What is the best browser to do this? How to make it clear to the program that it is necessary to isolate models from the browser? I understand that you need to run the browser executable? Which mode to choose?
Etc. And then, well, nothing happens at all. I have Windows 10.
Help please. Or, if you think possible, rip this scene for me: https://sketchfab.com/models/4702a19f22 ... e5d979660b Thanks
in advance to everyone who will help understand the process and get the result.
