problems with JS liberias in Ribbon Workbench

Hello experts,

I'm trying to create a workflow from ribbon, I'm following this tutorial.

ribbonworkbench.uservoice.com/.../132235-create-a-workflow-short-cut-ribbon-button-no-code

The problem lies in the part where the JS libraries are added, I do not know where to find those libraries since in the search engine I can not find anything.

I am using CRM Dynamics 2016

Any answer would be very helpful.

Thank you very much to all.
regards
