Live Chat from Desktop App

Live Chat from Desktop App

Hello,
I'm trying to add a live chat support to my desktop app.
1. Is this a good idea with Zoho Support?
 I think it is simple, add button to my desktop app that opens a chat window?

2. Can I pass some parameters (that will be provided from my app) while opening the chat window (like Name, email, and maybe a custom field with activation key) ?

Thank you, Davor
