Add code to track completion of Rise course

Hi community peers, my team would like to add some code tracking the start and completion of Rise course (not hosted on LMS). Starting code was added to index.html and successfully worked, but the completion tracking code added to goodbye.html page didn't, as this page never appeared when the course completed (we are sure if we can have the page displayed, the code would work).

Does anyone know how we can have the goodbye.html displayed, or track the completion by any other means? Thanks a lot in advance.
