Postman example of how to generate a JWT token for the Zephr Squad API

Hi,

I'm trying to generate a JWT token using postman but the documentation talks about pulling down a java repo to generate this.  I'm not coding in Java and need to know how to generate this JWT on a test run basis as I'll be integrating our .net core automation tests with zephyr squad.  Is there a simple example of how to generate this JWT?
