How to integrate Auth0 credential from my webapp to access my Zendesk API ?

I have an active Auth0 account.

I have a node js web app running in my local server. I have created and connected an Auth0 tenant for it.

I am able to login my webapp using my Auth0 connection itself. It is working fine.

 

I also have activated OAuth client in my zendesk . I am able to generate a bearer token for zendesk api. With that bearer token, I am able to create a Zendesk ticket.

Now, my requirement is:

I have a button in my webpage, (which is already logged in with Auth0 credential). Now, on clicking that button, i need to pick details from that form , and create a zendesk ticket using zendesk api - in  such a way that the user cant find , it is internally calling zendesk api.  (Only when the Auth0 authentication is alive for that web page user)

 

Thanks,
