Generic Plugin add button to view

Hi, I am new to OJS, and I am developing a Plugin to create a PDF document (using the FPDF library) that contains the data of an article (author, date on which it was the revision, title, and if it was accepted).
I had created a DAO class to access the information in the tables and feed the program to create the PDF with the info I need.
But, I can not find how to add a Hyperlink through the Plugin to the View / submissionReview / {$ id} without modifying the source code of it.
Could you tell me where I can find information to do this?
