Example code to add button (or hyperlink) to ticket display?

Hi All,

I’ve been hunting for some example code somewhere but haven’t managed to
find any.

I want to (cleanly) add a button or hyperlink to Ticket/Display.html
that links to (for example)


If anyone can point me in the right direction I’d appreciate it.

Oh, and I want to do it cleanly - which I think means using a Callback?

Any assistance/advice much appreciated,
