Assume this part of the asap widget JS object part. What do I need to place instead of "tokenValue". If I need to generate it with JWT secret, what should I use for a token before encryption? 

I read the documentation but didn't get what is exactly this token is? Is it unique for each user? If yes, then how to generate it. I can encrypt anything with JWT, but what data do I need to encrypt with it?

Can you show me an example?
