BUI - Fetch thread headers

Summary

Fetch Customer name, Account name + date of incident threads

Content

Hi, 

I am new to BUI extensions. I apologize in advance if this question was already addressed.

I am trying to retrieve the full incident thread (including open notes and responses). I would also like to retrieve the thread headers with the customer name, account name, and date. 

I was able to get the content, but unable to get the headers. How can I accomplish this?

I attached a code sample of what I have already tried. 
 

Thank you, 

Eitan
