Call a BI Publisher report from contract approval notification

Summary:

I modify the contract approval notification to have the link to open the Bi Publisher report like below. But this is not a hyperlink. How can we make it as a hyperlink and give a name. In excel template, we can use function hyperlink(). Not sure about RTF. I check other notification like PO approval that they can open a PO. But I am not quite sure how it work. Can someone give me a hint on how to do that.
